Expedia.com, one of the world's leading full service online travel sites, released a study last week, showing passenger behaviours that people find most annoying on a plane.
The survey asked 1,000 Americans to rank the most annoying on-board behaviours. The response showed that "rear seat kickers", who use their feet to attack a fellow passenger in front, have passed "inattentive parents" from last year to be the top offenders, with a 67 per cent vote.
Following "rear seat kickers" are "inattentive parents" (64 per cent), "the aromatic passengers" (56 per cent), "the audio insensitive" (51 per cent) and "the boozer" (50 per cent).
Seat wars are most likely to cause troubles in a plane. The survey showed that just 23 per cent of those surveyed ask permission of the passenger behind them before they recline. When the front passenger suddenly reclines his seat into your lunch in the tiny shared space, some people choose to kick back.
When onboard incidents like this happen, about 12 per cent of those surveyed say they would record the incident, and 6 per cent say they would use Twitter and other social media to shame those passengers. Only 22 per cent would talk directly to the offending passenger.
"Expedia's Airplane Etiquette Study is a lighthearted reminder that few places require more attention to etiquette than the inside of an airplane," said John Morrey, Expedia's vice president and general manager.
"You're in a tight space at 30,000 feet with hundreds of fellow travelers, so even the small things - helping your neighbour stow a bag or switching seats to put a mom next to her child - can make a huge difference."
