Once you make it to your cramped seat after getting past the long check-in line and security, the hunger kicks in. You realize that in your Heart of Darkness journey to make it to your plane on time, you forgot to eat. Now you've got four hours, and your choices include pretzels, really salty peanuts, or some sandwich that is packed so airtight, it could probably stay good without being refrigerated for at least a few days. And the kicker, of course, is that it will cost you an arm and a leg.
The solution is simple: get on board with any of these ten snacks so you don't go hungry, you eat healthy, and you don't spend too much money. That will make the flight a little easier.
