flightWhile celebrities are making headlines for their rude in-flight behavior, you certainly don't have to be famous to be an annoying person in the sky. Our friends at TheGloss are talking about the 10 celebs they'd avoid sitting next to on a flight -- but we just want to know what everyday passengers irritate the crap out of you when you're up in the air.

Tell us: Who's the most annoying passenger to sit next to on a flight?
