At Travolution we like a silly survey as much as the next person especially if it's about consumers' annoying habits.
So, the headlines from Travelocity's Rudeness Poll of US and Canadian travellers on bad travel behaviour are as follows:
Let's start with who you might not want to sit next to:
Passengers with poor hygiene, say 45% of those polled followed by coughing and sneezing travellers, 30%.
Loud and obnoxious travellers, particularly those that swear, are an annoyance for 56% and kicking the seat for 50%.
And then, arguing families, 31% (erm, well, airports are stressful places!), boisterous children, 28% and rowdy college students, 24%.
Opinions on overweight passengers are also strong with 80% thinking they should be allocated two seats and 44% saying it should be at no extra cost.
Other common irritations include:
29% are annoyed by travellers boarding with over-sized carry-on luggage - yes, we agree, if you can't carry it, check it in!
Canadians are more irritated by poor queue discipline than Americans but we think a bit more time spent at some European airports might cure that!
And, passengers in a rush to get off the plane on arrival are annoying for 57%.
Got any of your own to add to the list?

I hate sitting next to someone who somehow thinks they know more about flying the aircraft than the captain, judging by the fact that they seem to think the seatbelt sign somehow does not apply to them.
On a recent flight I was annoyed by a "Prima Donna". Fussing about her hand luggage, fussing to be the first one off the plane, rude to the cabin crew. First time I had flown BA so maybe that's the sort of passengers they attract.
Well if you are not only talking about flying then it has to be the whole towel on the sun lounger at dawn thing!
