United and Continental (which merged in 2011) offer 3 different snack boxes varying in health value, with the most popular being a convenience store goodie bag of goldfish crackers, jelly beans, salami, chips, and cookies. They also have a healthier Tapas box with hummus, gourmet crackers, and natural almonds. Sadly their organic snack box is no longer offered. United and Continental serve the exact same inflight snacks and meals within the U.S. (except for an Angus cheeseburger that Continental serves exclusively).
Delta (which owns Northwest) offers the Delta’s Eat menu on some flights. The menu has two snack boxes, one with a convenience store assortment of crackers, spreads, and chocolate (above) and the other with The Gracious Gourmet Mediterranean Vegetable Spread, organic Dr. Kracker Snackers, and other healthier sounding goodies.
JetBlue offers four different snack boxes that appeal to your mood and fitness goals. Do you want to Beef Up, Cheer Up, Shape Up, or Power Up? Some highlights here are Brothers All Natural Fuji Apple Fruit Crisps and Emerald Natural Almonds.
