A United Airlines flight was diverted when a fight broke out on board over the use of a $22 gadget that prevents someone's seat from reclining.
The male passenger is alleged to have installed a Knee Defender on the seat in front of him, preventing the seat from reclining, USA Today reports. The man was in the "economy plus" section, which offers an extra four inches of leg room.
He was asked to remove the device, which isn't prohibited by the Federal Aviation Authority, but refused. United Airlines spokesman Charles Hobart said the airline doesn't allow such devices.
The Associated Press reported the woman in front, who was angry she couldn't recline her seat, threw a glass of water at the man and the flight was forced to land in Chicago.
Hobart said the feuding passengers were removed from the flight and it continued to its destination, Denver, Co., but no charges were laid.
