Before you buy a snack box or two for that long flight, consider what's inside. Each food item served on airlines this year averaged about 400 calories -- and not all of those were healthy calories either.
Virgin America, for at least the third year in a row, took the top spot with 4.5 stars out of a possible 5. The survey warns against the airline's individual snacks and suggests the granola, yogurt and fruit breakfast and the protein meal with hummus, nuts and tuna.
The ratings were overseen by Charles Platkin, public health advocate and a professor at Hunter College and the City University of New York's School of Public Health, both in New York.
