As a business traveler, you know how difficult it can be to find a healthy meal while you travel from point A to point B. Often you’re forced to choose between eating fast food from a restaurant in the terminal, or putting up with whatever the airline has to offer. Not all airline food is the same, however, according to a survey conducted by DietDetective.com. In its 2013 Airline Food Survey, the website rated meals served by 12 North American airlines. It assigned a score of one to five based on eight criteria including nutritional value, calorie count, improvement over last year and menu creativity.
