Eating stinky food, clogging the toilet, or dousing yourself in perfume while on an airplane will make you pretty unpopular with your fellow travelers. While you might think you're a considerate air-travel comrade, you might not be aware of some things you shouldn't do on airplanes. Unless you have your own private jet like Lady Gaga, or if you're spend-happy enough to spring for a first-class ticket, being trapped in a steel tube hurtling through the sky in very close quarters with other passengers can be unpleasant. In order to get where you're going fast, you give up a lot creature comforts, including your personal space.
