Most annoying passenger behaviour on planes

With ultra-long-distance flights of 18 hours-plus on the horizon for Australian travellers, the issue of what's OK or not OK for one's fellow passengers takes centre stage.

While the aisle-galloping infant, the armrest hog and Mr Stinky can be tolerated for a flight of an hour or two, multiply that by a factor of five and tempers could explode.

The 2018 Airplane Etiquette report from Expedia put the spotlight on the inflight behaviours that annoy us most, and top of the list is the seat grabber, the one in the row behind who finds it necessary to get hold of the top of your seat and yank it back in order to hoist themselves upright.

Next is the inattentive parent, doing nothing to calm or comfort their distraught child, closely followed by the odour-enhanced passenger with an aroma you could carve.

Following in descending order of offensiveness are the personal space invader, the shouter and the queue jumper – slithering through passengers waiting to leave the aircraft just so they can spend more time waiting at the baggage carousel. The food fetishist toting their own pungent BYO meal and the bin hog complete the list.

Missing altogether is the seat recline enthusiast, who hits the button while the plane is still on the ground, then needs to be reminded to put it upright for meals. Not long ago the seat recline issue was a major cause of discontent. Perhaps bad inflight behaviour is also subject to the whims of fashion.

The seat grabber (60%) – a passenger who constantly bumps and grabs the seat in front of them when they get up out of their seat.
