With air travel comes a bombardment of fees for just about everything you might imagine. A snack that isn’t a small bag of pretzels? That’ll be $8. A blanket because your neighbor insists on keeping their air nozzle going full blast? Another $6. Then the most hated of all: the checked baggage fee. That $25 charge for the convenience of packing more may be annoying–but it also makes your air travel experience better.
