Flying economy comes with its fair share of woes such as limited legroom and subpar snacks, but nothing is worse than settling into your seat and having the person in front of you recline well into your 31 inches.
Lonely Planet reports Christopher Jon Sprigman and Christopher Buccafusco, two N.Y. lawyers, wanted to find out just how much we value those extra inches between ourselves and the person in front of us.
They surveyed a few hundred people and found that recliners wanted more money for not reclining than recliners are willing to pay for reclining.
Money aside, there are other incentives on a plane such as drinks and extra peanuts.
The lawyers conducted the same experiment but with beer, wine or chips.

More people were willing to offer up the incentives and more people were game to accept.
Lonely Planet reports Springman has been taking his experiments into the real world.
"When I'm in the seat in front I say to people: 'I'd like to recline but I don't want to make you uncomfortable so can I buy you a drink?'" he said.
It seems that just acknowledging the person behind you is enough.
Springman says that most people were happy just to have been offered the drink and didn't mind the reclining.
On certain airlines, passengers are just happy to make it onto the plane, not have to de-board for any reason and get to their destination on time.
