The following is a survey of 12 major North American airlines’ snack and on-board food offerings conducted by DietDetective.com and health advocate, Dr. Charles Platkin, from HUNTER College and City University of New York School of Public Health. The survey assigned a “Health Score” (5 stars = highest rate, 0 star = lowest) based on eight criteria including health of meals and snack boxes, health of individual snacks, healthy offerings, calorie levels (snacks, meals, snack boxes), improvement from last year’s survey, menu innovation and cooperation in providing nutritional information. The survey includes health ratings, average calories per airline, cost, comments, food offerings, calories, and exercise equivalents. The average number of calories per food item for all airlines last year was 388. This year it’s 360 calories per food item — a drop! Check to see how your favorite airline fared. Of course, in-flight meals vary so offerings on your next flight may differ from what Dr. Platkin sampled below.
