Are airline meals in the US really getting more fattening? The calorie data, 2012–2020

For six straight annual surveys, US airline menus told a consistent story: portion sizes crept up, and average calorie counts climbed with them. What rarely gets mentioned is that the same survey then reversed itself — and had already done so before most coverage of the "meals are getting more fattening" trend caught up with it.

The figures come from a single running source: the annual airline food investigation run by DietDetective.com and the Hunter College NYC Food Policy Center, led by nutrition researcher Charles Platkin. Each year the study contacts major US carriers for nutritional information on their inflight meals, snack boxes and individual snacks — historically concentrated on domestic and transcontinental routes — and publishes a health-score ranking alongside average calorie counts per menu item.

Six years of rising calories, 2012 to 2017

Averaged across every menu item the study tracked, calories rose almost every year for six years running: 360 in 2012, 388 in 2013, 397 in 2014, 400 in 2015, a small dip to 392 in 2016, then 405 in the 2017-18 edition — a cumulative rise of 45 calories, and the highest figure the study had recorded. That six-year climb is real and independently checkable across each year's published report.

Average calories per airline menu item rose in five of six years between 2012 and 2017 — then fell in the very next study.

Which airlines actually drove the numbers

The headline average hides a wide spread between carriers. In the 2017-18 study, Air Canada had the lowest full-meal average of any airline surveyed, at 377 calories, while Delta's meals averaged 559 calories and Hawaiian Airlines topped the table: its complimentary meals on longer Pacific routes ran as high as 1,485 calories, pulling its meal average well above every other carrier. Individual snacks varied even more sharply — JetBlue's averaged just 142 calories against Hawaiian's 460 — because "snack" covered anything from a small biscuit pack to a substantial hot item depending on the airline and route. None of this is a single-airline fact standing in for the industry: it is the spread the study itself reported that year.

The reversal the "getting fatter" headline missed

Here is the part that undercuts a simple "still climbing" narrative. Diet Detective's 2018-19 edition, released in December 2018, put the average at 373 calories per menu item — a 32-calorie fall from the 405 recorded the year before, roughly an 8% drop. Its following edition, published that November, held almost flat at 375 calories. By the time any commentary describing airline meals as "getting more fattening" would have been written using this dataset, the same source had already published two consecutive editions showing the opposite: calories down, not up, on the prior peak.

That does not erase the 2012-2017 climb, which is well documented and consistent across each year's independently released report. It does mean that treating 2017 as the end of the story, rather than the peak of it, overstates the case. The accurate read is a rise, then a correction — not a one-way trend.

What the data does not cover

The study's scope is narrower than "airline food" as a whole. It surveys roughly a dozen US carriers, weighted toward domestic and transcontinental routes, and does not extend to international airlines. That matters because several Middle Eastern and Asian carriers run substantially more elaborate meal service, particularly in premium cabins, than anything in this dataset. The 360-to-405-to-373 sequence describes US domestic economy dining specifically — not a global picture of inflight catering, and not a claim about any one airline's current menu, which changes between editions.

What it means for a two-meal long-haul flight

Even at the 2017 peak, two airline meals came to roughly 810 calories, and at the more recent 373-375 average, closer to 750 — in both cases comfortably under half of a commonly cited 2,000-calorie daily reference intake for an average adult, before any snacks or drinks are added. The bigger driver of a passenger's overall in-flight intake is less the base meal and more what surrounds it: snack boxes, alcohol, and terminal food bought before boarding.

• Meal calorie counts vary far more by airline than by year — Air Canada's 377 versus Hawaiian's near-1,000-calorie long-haul meals is a bigger gap than any single year-over-year change.
• Individual snacks are the least consistent category: a "snack" can be a 142-calorie biscuit pack or a 460-calorie hot item depending on the carrier.
• Buying food in the terminal, rather than relying on the inflight menu, remains the most reliable way to control calorie intake on a flight, since it removes the guesswork over what a given airline's "meal" or "snack" actually contains.
