Don’t put your bare feet up on the seats or the bulkhead wall of a plane. And do not drape your hair over the seat back so it’s directly in front of the passenger seated behind you. This is even worse on a cramped regional jet.
The type of aircraft means there’s no seat back entertainment screen, so I suppose that is a saving grace: the hair isn’t covering up the show the passenger in the row behind was watching. But that also means they have nothing to distract themselves from The. Hair.
Some people might speak up and say, “Excuse me?”
While others would pull the hair, dip it in coffee or gum, or pull out a pair of scissors. Remember that while TSA once known as the acronym for “Taking Scissors Away,” passengers are now allowed to bring scissors through airport security as long as the blades extend no more than 4 inches from the pivot point.
Can you think of worse everyday on board behavior than a passenger sticking their hair into the space of the passenger behind them? Clipping nails, maybe?
