The 19 Most Annoying Passengers to Sit By on a Plane

Inattentive parents and flyers that kick the back of other passengers' seats are the most inconsiderate travelers in the skies, says a new Expedia survey released today.

The study, conducted by Northstar, surveyed 1,001 U.S. adults on the in-flight behaviors that bother them the most. The violations ranged from smelly and talkative seat mates to line jumpers and frequent bathroom users.

But nothing makes a flyer cringe as much as a crying children. The Expedia survey found that 63 percent of travelers "often feel annoyed" at parents traveling with loud children and that 49 percent would pay extra to sit in a quiet zone.

However, Skift's consumer survey found that only 15 percent of respondents would be willing to pay an additional fee to sit in a child-free zone.

A few other fun findings from that Expedia study are that 22 percent of travelers consume more than two alcoholic drinks during air travel and 38 percent of travelers believe whoever sits first can claim which armrest they use.

The full list of in-flight offenders is below, ranked from most to least annoying:
