Airlines Should Charge You $0.01 to Use the Bathroom

Did you see the article about United removing olives from their inflight meals leading to a cost saving of $40,000 per year? Here it is, pass it on.

It’s quite astounding isn’t it?

Now imagine all the other things carried by passengers in the cabin. The weight of all their clothes. Phones, laptops, and tablets. The bottles of water, or liquid they’ve consumed in the airport bar before the flight. Olives seem even more insignificant now.

With airlines continually introducing restrictions, and in-turn “added-extras”, I decided to take a look at the cost of flying the smaller items we, currently, pay no attention to bringing onboard.

Methodology

In 2017 I wrote a post about airlines undercharging for fuel. Sadly that post did not factor in load-factor (how full the plane was). Secondly, the prices for fuel in that post are now out of date. Updated fuel costs from IATA show an average $1.87 per gallon versus $1.45 at the time of writing in 2017.

Five Thirty Eight writers Luke Jensen and Brian Yutko created a more detailed model for weight to fuel cost in June 2014.

They calculated each marginal pound added in weight from carry on items cost an additional $0.01 USD per / lb for short-haul routes (500 miles) and $0.073 USD per / lb for cross-country flights (2,500 miles).

Adjusting for fuel cost (in June 2014 jet fuel cost $2.88 USD / gal) vs $1.87 (-35%) today (Feb 2019) this equates to an additional $0.006 USD per / lb for short-haul routes (500 miles) and $0.047 USD per / lb for cross-country flights (2,500 miles).

Converted to kilograms (because I don’t understand imperial) equals an additional $0.003 USD per / kg for short-haul routes (500 miles) and $0.02 USD per / kg for cross-country flights (2,500 miles).

These calculations assume a load factor of 85% (how full the plane was), equal to 122 passengers, on a Boeing 737-700, a commonly used plane (especially by Southwest airlines) on short-haul routes of 500 miles (equivalent to San Francisco to San Diego) and cross-country routes of 2,500 miles (East to West Coast USA)

I simply Googled weights of common items that might be taken onboard.

Assuming you carry all these items onboard a 500 mile flight, you’ll cost the airline $0.09 more in fuel. Not much when compared to the ticket cost, but remember this calculation does not consider the weight the airline has already accounted for (your weight, bags, etc.).

If everyone does the same, all 122 passengers, that’s an additional $10.94 per flight, or $21.89 if you count the return leg too. If the flight operates everyday for a year that’s an addition $24,000 in fuel costs for the airline!

On a longer flight of 2,500, or across the USA, these items will cost the airline $0.65 additional in fuel. Carrying on 1 litre of water (in a bottle or your body) will cost the airline $0.02 per passenger, or $2.63 for a flight of 122 people.

All items, again assuming the route operates once per day return, adds up to an additional fuel cost of $175,000.

If airlines asked passengers to travel naked on this hypothetical cross-country route, they could save $11,500 in fuel costs each year. You can see why even the cost of a single olive adds up quickly.

Back of napkin maths

Often airlines might run upwards many variations of trans-America routes. Assuming 100 variations of routes, running return once per day (probably an underestimate), that’s an additional $17.5 million in fuel costs for the additional weight per year using my numbers!

Thinking globally (100,000 flights per day), this number could easily cross many billions in savings per year (and a whole lot of emissions!).

Improvements

These are very rough calculations for a single type of plane over fixed distances. It would be great to see an analysis like this done on a real per-route basis.

tl;dr

On a cross country USA route of 2,500 miles, an airline needs to pay $0.02 in additional fuel costs for you to carry on 1 litre of water. A bladder can hold around 0.5 litres, or $0.01 worth of fuel on the same flight.

269 billion litres of jet fuel was burned in 2017 — Enough fuel to fill 5.4 billion VW Golfs

Fuel is one of the biggest operating expenditures for airlines — and you’re probably being undercharged for it (at least in 2017).

We know that the airline industry is a heavy polluter. The fact an A380’s fuel tank has a capacity of 320,000 litres (84,500 US Gal) hints at just how much fuel is required to fly across the world.

Now consider the volume of commercial flights each day. Some estimates suggest this number exceeds 100,000 per day. That’s a lot of jet fuel.

I decided to delve into how much fuel airlines are using (and what it costs them).

Methodology

The US Bureau of Transportation Statistics publishes data on fuel consumption and fuel cost reported by US based airlines for both domestic and international operation.

I selected the airlines classed as major (>$20 million revenue / year) that were operational for the whole of 2017 (the last year with full data reported at the time of writing).

Other statistics in this post were pulled from Wikipedia. Citations here.

Fuel consumption of major US airlines 2017

Fuel consumption and fuel cost of major US airlines 2017

Download chart.

In total the 17 major US airlines consumed 64,853,949,435 (64.9 billion) litres of fuel in 2017. 42.7 billion litres was used for domestic routes and 22.2 billion litres on international routes.

This amount is enough to fill 1.3 billion VW Golf’s with a 50 litre fuel tank (of course, you would not want to use jet fuel)!

Unfortunately I do not have the exact figures for how many flying kilometres this amount of fuel represents. But I can estimate…

According to this Wikipedia article, jet fuel weighs 0.81 kg/l. This equates to US airlines using 52.5 billion kilograms of fuel in 2017.

Turing to Wikipedia again, a Boeing 787-9 burns 5.77 kg of fuel per km. Using this as the average figure for fuel efficiency across all US major airlines would mean that 9.1 billion kilometres was flown in 2017.

Check my calculations here.

Full table.

These airlines paid $28,934,684,000 USD ($28.9 billion) for fuel in 2017.

You will notice American Airlines used more fuel than Delta (13.5 vs. 12.9 billion litres), but paid less for it ($5.75 vs $5.94 billion USD) in 2017. This is because airlines strategy for buying and holding fuel differs. In fact, very large teams working for airlines are solely dedicated to the task of buying fuel, for good reason.

Cost paid per litre of jet fuel by US major airlines 2017

Download chart.

There is a fairly large range in price paid per litre of jet fuel between these airlines. Frontier Airlines fuel team are doing the best job paying around $0.42 per litre in 2017. ExpressJet paid $0.67 per litre! This largely the result of economies of scale. Frontier bought 915,573,331 litres of fuel in 2017, whereas ExpressJet bought only 2,278,817 litres.

Worldwide jet fuel consumption

According to this Forbes article, there were 4 billion air travellers in 2017. The US Bureau of Transport and Statistics reports 965 million of these, or 24%, were from the US.

If 64,853,949,435 litres represents roughly 24% of all worldwide jet fuel consumption (US consumption), in 2017 airlines consumed 268,824,660,869 (269 billion) litres of jet fuel worth an estimated $120,561,183,333.

Taking the 2017 world population (7.5 billion), that means 35.8 litres of jet fuel was burned per person in 2017! And this is an underestimation (see improvements).

Improvements

The final calculations for world fuel consumption in 2017 need to be improved. I only considered fuel consumption for major US airlines, and omitted smaller airlines operating in the US and non-commercial traffic.

This means that fuel consumption in the US will be higher than the figure I used (64.8 billion litres), and thus so will the figure for fuel consumption for worldwide airlines.

tl;dr

An estimated 269 billion litres of jet fuel was burned by the largest commercial airlines in 2017 — 35.8 litres for each person on the planet.

Pilots are Exposed to the Equivalent of 75 Chest X-Rays per Year

I fly a lot.

I remember when I first started travelling significantly, on one flight a woman sitting next to me told me of her worries about the radiation she would be exposed to during the long flight.

The thought lingered in my mind for a few seconds, but I never thought any more of it.

Until a friend posed this question over dinner a few nights ago…

Methodology

I looked at radiation doses using data from radiologyinfo.org (via The Guardian) and compared it to findings from a number of studies investigating radiation exposure during commercial airline flights.

Results

Radiation dosages

Let’s start by looking at radiation guidelines, and set some points of reference to make this data more quantifiable.

Event Radiation reading, millisievert (mSv)
Single dose, fatal within weeks 10,000
Typical doseage recorded in those Chernobyl workers who died within a month 6,000
Single does which would kill half of those exposed to it within a month 5,000
Single doseage which would cause radiation sickness, including nausea, lower white blood cell count. Not fatal 1,000
Accumulated doseage estimated to cause a fatal cancer many years later in 5% of people 1,000
Max radiation levels recorded at Fukushima plant yesterday, per hour 400
Exposure of Chernobyl residents who were relocated after the blast in 1986 350
Recommended limit for radiation workers every five years 100
Lowest annual dose at which any increase in cancer is clearly evident 100
CT scan: heart 16
CT scan: abdomen & pelvis 15
Dose in full-body CT scan 10
Natural radiation we’re all exposed to, per year 2
CT scan: head 2
Spine x-ray 1.5
Radiation per hour detected at Fukushimia site, 12 March 1.015
Mammogram breast x-ray 0.4
Chest x-ray 0.1
Dental x-ray 0.005

Download data.

The scientific unit of measurement for whole body radiation dose, called “effective dose,” is the millisievert (mSv).

Most routine x-rays expose us to very low levels of radiation. A dental x-ray exposes a patient to 0.005 mSv. Putting this into context, the lowest annual dose at which any increase in cancer is clearly evident is 100 mSv, or 20,000 dental x-rays.

Radiation exposure during flying

Route mSv per 100 block hours mSv per 1 hour
Seattle to Portland 0.03 0.0003
New York to Chicago 0.39 0.0039
Los Angeles to Honolulu 0.26 0.0026
London to New York 0.51 0.0051
Athens to New York 0.63 0.0063
Tokyo to New York 0.55 0.0055

Download data.

Based on studies, the radiation dose rate on 6 typical commercial airline flights at an altitude of 35,000 feet varies between 0.0003 mSV and 0.00055 per hour (mean average = 0.0004 msv). It is important to note that radiation dose levels represent a complex function of duration of flight, latitude, and altitude.

That said, assuming the average flight times from the route data from my post: The Worlds Shortest Commercial Flight. 2 Minutes to Fly 3 Kilometres, the graph and table below show estimated radiation exposure for the 38 longest (by time) routes.

View calculations.

The mean average mSv for the 38 longest flights by time, with durations between 15:20 and 17:35, is 0.0064 mSv. Put another way, just under 6.5% of the radiation you would receive from a chest x-ray. The longest flight by time, Auckland to Doha at 17 hours 35 minutes, exposes passengers to and estimated 0.007 mSV, which is about 0.32% of the average radiation you would be exposed to each year naturally.

Frequent flyers

In 2017, business traveler Tom Stuker became the world’s most frequent flyer, logging 18,000,000 miles (28,968,192 km) of air travel on United Airlines over the last 14 years — that’s 722.8 times (51.6 times per year) around the world (assuming 40,075 km equatorial circumference of earth)!

Assuming an average flight speed (550 mph), Stuker’s 18,000,000 miles would translate into 32,727 hours (2337.6 hours per year) of flight time or 212 mSv (15.12 mSv per year) of radiation. About the same as a CT scan of your abdomen and pelvis each year.

Most pilots typically log under 1,000 hours per year so airline workers would have risk levels about half that of Stuker’s (less than 7.5 mSv per year).

tl;dr

Even if you’re a frequent flyer, the risk from radiation to your health is low. Pilots are exposed to no more than 7.5 mSv per year, equivalent to 75 chest x-rays, well below the lowest annual dose at which any increase in cancer is clearly evident (100 mSv).

Gift Buying Guide: The Best Private Jets Under $500 Million

I’m fascinated by airline operations. Many major airlines have fleet sizes upwards of 800 aircraft. Now consider many of these planes operate non-stop, requiring hundreds-of-thousands of litres of fuel for each journey, and a small army of staff to keep running, operating costs can quickly add up.

Recently reading an article titled, “Qatar’s emir ‘gives $500m private jet to Turkey” (a Boeing 747-8i), I started exploring the costs of operating your own private jet.

With Christmas quickly approaching, I’ve created a (tongue in cheek) buyers guide for private jets. When a pair of socks won’t cut it, perhaps a private jet will suffice?

Methodology

The following analysis uses aircraft data (including list prices, number of seats, and fuel efficiency) sourced from aircraftcompare.com. Jet fuel prices used to calculate fuel costs were obtained from IATA in October 2018.

The A380, the largest commercial passenger plane with a potential capacity of 900 passengers, is offered by Airbus as a private jet. The company has reported 5 orders, potentially worth almost $2 billion. Many articles detailing the incredible configurations of private A380’s exist online (including flying garages).

At the other end of the scale, smaller regional private aircraft with ranges below 5,000 kilometers (London to New York is 5,567 km) can be purchased for under $10 million.

The current Air Force One (a highly modified Boeing 747) has room for 102 passengers. Each seat, based on the list cost of $390 million, is worth $3.82 million each. A modified Boeing 747 8 VIP with an average cost of $295 million has just 32 seats, making it the private aircraft with the highest cost per seat at $9.22 million each!

Only 3 planes have cost per seat less than $1 million. The Boeing BBJ, is the only mid to long-range jet (range 7,223km) with a cost per seat less than $1 million.

1 Boeing 747 8 VIP $8.62 $0.27

View full list.

Don’t forget, even after spending millions on a jet, you’re going to need to fuel it too (along with all the other ongoing costs). The most fuel efficient jet in our list is the Boeing Business Jet. Assuming it flies at full capacity (63), each passenger will cost $0.02 per kilometre they travel. In contrast, each passenger on a 747 8 VIP will cost $0.27 per kilometre they travel (max pax 32).

The A380 Private Jet costing $10.35 per kilometre to fly and Air Force One costing $8.62 per kilometre to fly are much more fuel efficient when compared to the 747 8 VIP because they all have the potential to carry significantly more passengers (both over 100).

Improvements

In some cases, the aircraft pricing data seems slightly inaccurate (perhaps out-of-date). For example, Boeing and Airbus publish the list prices of aircraft on their website. The lists do not include private jets, but in some cases the private jet cost is lower than the commercial (which does not appear correct). As such, the accuracy of this analysis would be improved if pricing and specifications were obtained directly from the manufacturers, if possible.

tl;dr

Long-range private jets (range greater than 10,000km) can be purchased for upwards of $39 million (Gulfstream V) to $402 million (Airbus A380 Private Jet). Don’t forget the operating costs though. An A380 will cost around $160,000 to fuel.

The Billion Dollar Airline Routes

I like to board last. I’ve never understood the appeal of being on the plane any longer than I need too (I’m yet to travel in business class).

A lot of my travel is international, and it often involves flying on the giants of the sky, including Boeing 747s (not for much longer) and the huge Airbus A380.

As I waited to board an A380 on a trip to San Francisco from London this year I did some back of the napkin (literally) calculations at the departure gate. Assuming the 469 seats on the flight were occupied sold at the approximate cost I paid for the ticket ($1000), equals a potential ticket revenue for that flight of $469,000 for the airline. Bear in mind, it is estimated an A380 costs between $26,000 – $29,000 per hour to operate (and the flight is almost 12 hours)!

Clearly my calculation is far from accurate. Though it got me thinking, with multiple flights being operated daily throughout the year, some routes might be generating billions of dollars in revenue yearly.

The company produced a report in February 2018 titled: “Key Facts Behind the World’s Busiest Routes”. It details the world’s busiest trunk routes in terms of the volume of flights that operate on them. For each of the 20 routes the report lists various statistics for each route from passenger numbers to average route length.

To estimate route revenue I used Skyscanner (on 04/09/2018) to calculate the cheapest economy return flight (5-day) for the 20 routes 6 months into the future (04/03/2018 – 08/03/2018)

Using these statistics, I performed the following analysis.

The average stage length for the 20 routes is 1384.05km. 19 of the 20 routes could be considered short-haul flights (below 2,562km). The only long-haul route (cross continent) is London (LHR) to New York (JFK) with an average stage length of 5,536km.

1 of the routes operates in North America / Europe, 1 in the Middle East, 2 of the routes are in Europe, 2 in North America, and 14 in Asia.

The choice of aircraft is an important one. Newer aircraft are more fuel efficient, others can fly longer distances.

19 of top 20 busiest routes use Airbus A318/319/320/321 aircraft. Given the majority of the routes (17) all operate outside North America (Boeing’s largest market) this is unsurprising.

The Boeing 737 still proves popular 38 years since it first rolled off the production line (15 operating). Interestingly, despite many routes being considered short-haul, the Airbus A380, with upwards of 469 seats, is operated on 6 routes.

Route revenues

Estimated revenue for top 20 routes 2018

Unsurprisingly the longest, and most expensive ($693) route by lowest ticket price (New York JFK – London LHR) generates the most revenue (over $2 billion dollars). The route carries 3,049,370 passengers yearly (ranked 8th by passengers of all routes) with 3,651,659 available. That is a is a passenger load factor of 84% (above the average load factor of 80% for all routes).

The other two routes that generate more than $1 billion are Hong Kong – Taipei ($1.52 billion) and Soekarno-Hatta International Airport – Singapore ($1.06 billion).

Route revenues for airlines with largest market share

Download chart.

British Airways is the largest operator on the New York JFK – London (42% of all flights) and generates an estimated revenue of $887,549,632.20. Assuming the average ticket cost is 20% higher than the lowest price I found (very likely) would mean this is a $1 billion route for BA. This is almost double the earnings of the two largest airlines on the second and third highest revenue generating routes.

Revenue per km

Given the comparatively short distance between Soekarno-Hatta International Airport (Jakarta) – Singapore  (880km) and large passenger revenue $1,519,775,162.00) means it generates the most revenue per kilometre flown ($63.25). Compare that to Soekarno-Hatta International Airport – Kuala Lumpur (1,127km) which generates just $5.82 per kilometre.

Improvements

Most of the calculations in this post rely on accurate average ticket prices for routes. Unfortunately I was limited to using SkyScanner to estimate average prices. The biggest improvement to this analysis would be to include accurate ticket revenues.

tl;dr

New York JFK – London LHR potentially generates $2 billion dollars in revenue from ticket sales each year.

Internet at 35,000 Feet. How Hard Can it Be?

Ten hours, possibly longer, stuck in a small metal tube with hundreds of other people each wrestling for the tiniest amount of extra space. Flying can be a chore.

Electronics powering music, movies and games, are staples of modern flyers that help to pass the time. Airlines invest millions in onboard entertainment systems to improve passenger experience.

A quick Google search will show you that many passengers, including myself, are now regularly asking if internet services are found onboard flights. The same search will also show you how poor these services can be, assuming they exists at all.

Boeing’s early in-flight Internet service, Connexion, launched in 2001 (since discontinued). 17 year later, how has the market for in-flight internet developed?

Methodology

Each year Skytrax put together a list of the top 100 airlines around the world using a range of variables. The most recent is the 2017 version. Due to the merger of Alaska Airlines (36) and Virgin America (43) I have reduced the list to 99, removing Virgin America.

For each of the 99 airlines I then visited their websites to identify if:

  1. they offer onboard internet
  2. the cost of internet services, if applicable

Not all airlines clearly document wether internet services exist. Many use the umbrella term “WiFi onboard”, however, in many cases this does not include internet access, instead just access to a network with inflight content (similar to that offered on traditional inflight entertainment systems). Those who did not explicitly document internet access were recorded as not to offer it.

Similarly, many airlines are slowly rolling out wifi. In some cases only a few routes served by an airline have in-flight internet, for others the coverage is more widespread. Due to lack of information about internet access by route the actual prevalence of internet onboard is not accounted for.

The cost of in-flight internet, which almost all airlines charge for, is rather complex. There is no unified standard for providing services, some airlines charge based on data usage, others by time, and in some case some by the originating country of the flight. Due to lack of standardisation, I only documented the airlines that offered free access or paid access to in-flight internet.

Finally, I assigned each airline a classification based on the routes they serve, either regional (only short/medium-haul routes) and international (at least one long-haul route), the assumption being that fewer regional flights will offer in-flight internet because of the shorter flight times.

The Worlds Shortest Commercial Flight. 2 Minutes to Fly 3 Kilometres

If it’s Tuesday, it must be Wednesday.

The Time Zone system counts 12 hours in either direction from Greenwich and meets up more or less in the middle of the Pacific Ocean. This imaginary boundary is called the International Date Line and anywhere it meets, an extremely strange thing happens. Time jumps ahead 24 hours – an entire day. If you fly from China to the West Coast of the US, for example, the jump can be particularly tough on the body.

Flying long-haul can be very tough on your body. Timezone changes mixed with hours of sitting uncomfortably (unless you’re lucky to fly business class or above) is not something many look forward too.

Timezone changes can work both ways. When Concorde was in operation (1976 – 2003) flying from London to New York you could arrive, in terms of local time, before you left. A New York to London flight took only 3 hours 20 minutes (the fastest journey was 2 hours 52 minutes and 59 seconds!).

How bad does it get? What are the longest plane journeys?

Methodology

I collected data from Wikipedia about commercial aircraft ranges and both operational and retired commercial routes for comparison.

The biggest limitation to flying distance is aircraft — it takes a lot of fuel to keep a plane in the air.

The Boeing 777-200LR (the LR stands for Long Range) is the aircraft with the largest potential range, 17,395km (the circumference of the earth is 40,008km).

Did you know? The aircraft with the longest ranges are: 1. Boeing 777-200LR (17,395km), 2. Airbus A340-500 (16,670km), 3. Boeing 787-9 Dreamliner (15,750km).

The longest route (distance) operated by a Turboprop aircraft is the Bombardier Dash 8 Q400 (1726 km / PD175).

All of the 10 longest flights are operated by jet powered aircraft. The longest route (distance) operated by a Jetliner aircraft is the Boeing 777-200LR (14,524km / QR 921). This is just under 3000km short of the aircrafts max operating range (17,395km).

Notably, flight SV 41 operated by an Boeing 777-300ER between Jeddah and LA takes about 16 hours 55 mins to cover 13,400km. However, flight UA 179 (San Francisco to Singapore) covers a longer distance (13,600km) but is 35 minutes shorter in duration (16 hours 20 mins) operated on a Boeing 787-9.

The longest journey (distance) ever operated was SQ21 Newark – Singapore (15,345km) and took 18h50m (ouch!). This route was flown by a A340-500 (max range 16,670km).

SQ37, LA – Singapore (14,114km) took 18h05m flown on an A340-500. This journey is almost an hour longer than QR921 Auckland – Doha (14,524km / 17h35m) currently flown on a 777-200LR. Both routes are about equal in distance and the direction of travel is the same. The time difference can be attributed to cruising speeds of each aircraft: 777-200LR = 1037km/h vs. A340-500 = 945 km/h — about 100 km/h slower.

Anyone who has spent 17 hours on a plane knows how tough it can be on the body. That said, flights where you spend longer in the airport then in the air can be frustrating.

The shortest route flown by time and distance is between Westray and Papa Westray in Scotland. The distance is 2.73km and the flight takes just 2 minutes. It’s a hotly contested route for airlines. In 2013 a one-way ticket was priced at £21 (a brief search did not uncover recent prices).

Interestingly, the 9th shortest flight by distance, Karpathos-Kasos Island (22km), takes just 5 minutes on the De Havilland Canada Dash 8.

Did you know? The shortest routes (distance) currently flown are: 3. Minami-Daito – Kita-Daito (12km / 15m), 2. Caye Chape – Caye Caulker (3.8km / 2m), 1. Westray and Papa Westray (2.73km / 2m).

I would like to compare how the flight duration differences changed based on average cruising speed of different aircraft.

British Airways’ IT Failure Cost the Airline €17,246 a Minute

Well, what a weekend it has been for British Airways.

Thankfully I wasn’t travelling out of Heathrow, my local airport, due to the long weekend here in the UK. However I do know of many friends who’ve had their holidays ruined by the “IT failure” that led to the mass cancellation of flights on Saturday and Sunday by British Airways.

The airline has been going through heavy cost-cutting over recent years. I’m almost certain the events this weekend have wiped out any savings they’ve made. Their share price has dropped by £175mm alone. Though how much might this fiasco directly cost the airline?

Methodology

Airhelp, a company that helps travellers claim compensation for flight delays and cancellations, put together a dataset detailing British Airways flights and estimated passenger numbers for scheduled departures this weekend (27/05/2017 – 28/05/2017) from airports around the world.

In this dataset they split out delayed flights and those that were cancelled. If you booked a flight that departed from Europe or was with a European airline, you  have rights under EU law if your flight is delayed or cancelled. The amount that can be claimed is determined by length of delay, length of flight and wether the flight was cancelled completely.

Using this data it was possible to estimate British Airways’ potential liability for passenger compensation for Saturday (27/05/2017) and Sunday (28/05/2017).

All figure are quoted in Euro’s (EUR).

Unsurprisingly Heathrow tops the list with a potential liability of €21,234,342.77. This equates to €7373 per minute in compensation (21mm / 2880 min)! Ouch.

Remember, one variable that affects the amount of compensation you can claim is the distance of a flight. As BA tend to fly in/out of the UK, passengers flying from/to airports further away from the UK can typically claim more. This is why flights departing from airports like Hong Kong have high total compensation liabilities (€477,352.64) in comparison to passenger numbers (619).

Overall, the average compensation liability per airport was €245,448.

As British Airways operates out of the UK, it is unsurprising to see compensation liabilities and passengers affected to be highest from British airports. Passengers flying British Airways from the US were the second worst affected (16k passengers / € 9.6mm compensation liability). There were significantly more affected BA passengers from the US than other countries (excluding the UK).

Average claim amounts

There is a fairly even spread of maximum compensation passengers are eligible to claim.

Typically airports a long distance from the UK – for example DXV, PVG, HKG – have the highest average amount passengers can claim in compensation (€771.43) as discussed above.

European airports typically have the lowest amount passengers can claim in compensation (€264.53) due to their distance from the UK (or total flight time).

Based on EU compensation rules, BA is potentially liable to pay €49,670,411.92 in passenger compensation for the two days of delays and cancellations this weekend. Or €17,246 a minute (49.5mm / 2880 min)!

Airlines Owe Passengers Over 3 Billion Dollars in Compensation (and Counting)

Passengers bumped on overbooked flights has been in the news ALOT recently.

Many flyers on EU airlines (or from EU countries) are becoming privy to the fact they could be eligible to claim compensation for delayed flight in Europe. Airhelp, a company that helps passengers claim compensation from airlines, advises delays over 3 hours are typically eligible for compensation.

If you live in the UK you’ll be aware of the huge liability banks have had for PPI payouts in the last 10 years. With many airlines operating on the brink of bankruptcy according to some sources; how much are airlines potentially liable for in compensation payouts?

Methodology

Airhelp, a company that helps passengers claim compensation for delayed flights, provided me with a dataset of airports around the world, number of delayed flights (and seats) eligible for compensation, and a calculated estimate of what the total potential liability was for each airport for compensation during 2016 (based on regulation EC261 which covers delayed, cancelled and overbooked flights). Note, compensation is paid by airlines, not airports. Therefore, this post highlights the airports with the highest number of delays, over-bookings, etc, but is not split out to consider individual airlines.

Whilst the dataset covers a large number of airports around the world (5000), only a subset of airports have data for delayed eligibly (574). This is for 2 reasons; 1) compensation rules differ around the world (see EU vs. US, for example) therefore it is difficult to produce accurate estimates for each geography. 2) Airhelphas a commercial interest in the EU market.

Airhelp provided monetary data in Euro’s (EUR). To keep currency consistency with my other posts on this blog I have converted all figures to US Dollars (USD) using the exchange rate of 1 EUR = 1.09 USD (correct 30th April 2017 via xe.com).

Additional datasets used were from the FAA (US) and CAA (UK) for total aircraft movements at each airport (to calculate the percentage of delayed flights within the US and UK). This data did not differentiate between arriving and departing flights (only departing flights are considered for compensation eligibility), I therefore assumed 50% of operation were departures (roughly in line with LHR figures).

The majority of airports were liable for less than 10 million in compensation during 2016 (241 airports), though 61 airports were liable for more than this.

241 airports were liable for more than 1 million USD, and 455 liable for over 100K USD, and 566 liable for over 10K USD. Only 9 were liable for less, with VST Stockholm Vasteras Apt bottom of the list with a liability to 14 passengers totalling $3815 USD (avg. $272.50 USD each).

The compensation liability for all airports considered (574) is 3 billion USD ($3,001,339,552.25 USD).

Airlines who flew out of Heathrow LHR during 2016 were liable for passenger compensation claims to the tune of $0.25 billion USD ($265,998,150.00 USD) — unsurprising given capacity issues at the airport.

Average compensation per seat groups at both end of the spectrum, 175 airports owe an average of $270 – $300 USD per seat (lowest claim possible is $272.50 USD), 174 owe an average of $630 – $660 USD (max claim possible is $654 USD). Note, values are per seat (not passenger) this is because a passenger can be delayed multiple times per year and thus eligible for more than one compensation claim.

UK airports make up all 10 of the worst airports for departure operations by compensation liability. 2.24% of flights taking of from LCY London City Airport were liable for compensation claims from passengers.

Note, this dataset only contains US and UK airports for comparison.

Improvements

There are two clear improvements that can be made to allow for a more comprehensive analysis.

Firstly, having access to addition compensation data for more airports with local compensation rules (vs. just EU) could provide interesting analysis into best regions for compensation, worst regions for liability, etc.

Secondly, accurate operations departure data for all major worldwide airports would improve calculations. Due to the datasets used, the above workings only consider some US airports and UK airports, whilst also use estimated commercial departure figures (departures=total commercial operations / 2).

tl;dr

Airlines who flew out of Heathrow LHR during 2016 were liable for passenger compensation claims to the tune of $0.25 billion USD ($265,998,150.00 USD). The compensation liability for all airports considered (574) is 3 billion USD ($3,001,339,552.25 USD).

We Are Now Taking Off From 22000 Feet

It is very likely you’re within 50km of an airport — even if it’s a very small one.

Passenger volumes continue to rise year-on-year, and newer, larger airports are needed to keep up with demand. My local major airport, London Heathrow (LHR), claims to operate at 98% capacity.

London alone has 5 major airports, and many fast growing commercial ones such as London Southend (SEN). Although if it’s actually in London is debatable!

With a recent inquisitiveness about airports, I began questioning. How many airports are out there? Where are they? Here are some interesting statistics.

Methodology

OurAirports maintain a comprehensive document of airports around the world. It currently lists over 46000 airports and includes information such as location, elevation, runways, and identification codes. This data was used to perform all analysis.

Perhaps to be expected the US has the most airports, but I did not expect it to be almost 18,000 more than the second placed country, Brazil. Although most of the airports in the US are classified a small (private) airports, 21.5k airports is still a huge number!

To give this some perspective, Mount Everest stands at 8848 meters — just 2000 meters higher than Siachen Glacier AFS Airport, India. In fact, this airport (heliport) would rank just outside the top 100 highest mountains. Sadly, it only serves a military purpose, but all credit to the pilots flying at that elevation! The highest large airport is Alejandro Velasco Astete International Airport in Peru at 3310 meters above sea level.

At the other end of the scale, Bar Yehuda Airfield in Israel lies 386 meters below sea level. The English Channel is only 120m deep.

No that’s not a typo, Pontiac Airpark Water Aerodrome has a runway that’s 36.5 km long (it is water runway for seaplanes). The longest traditional runway is at Qamdo Bangda Airport in China at 5.5km. The runway needs to be so long because of the elevation of the airport (4333m). When the air is thinner (at altitude) it takes longer for a plane to take-off and land.

The runway at Juancho E. Yrausquin Airport in Saba (in the Caribbean) runs a mere 396m, making it the world’s shortest commercial runways (excluding heliports).

Improvements

I would be very interested in analysing how much traffic some of the runways with notable characteristics receive and any associated accident information, especially those with a high elevation.

tl;dr

The United States has 21.4k airports. That’s almost 18k more than any other country.
