Of domestic U.S. carriers, United Airlines offers the most nutritious in-flight snack box, USA Today reports. The airline's Smartpack box ($5) includes granola, organic peach applesauce, and cheddar cheese. It's vegetarian-friendly and free of trans fats. However, the contents of the snack box add up to 810 calories.
Which airlines serve the least nutritious meals or snack boxes? Southwest and Northwest. Example: Southwest's Snack Pack includes "cookies, cheese sandwich crackers and dried fruit and nuts," according to USA Today.
Of course, airline food has never been confused with haute cuisine. I remember a hot breakfast I received on US Airlines years ago that included an omelet, plus bacon and sausage. Come to think of it, that meal was free, and I was traveling in coach. Oh, for the good old days of air travel.
P.S. Airlinemeals.net is a fun Web site in which travelers share photos and stories of the in-flight foods placed before their disbelieving eyes. Below is a photo from the site, of a meal served on TWA circa 1958-59. Can you identify the food? Or, more to the point, do you even want to?
