Punch-up at 30,000ft: Shocking moment two men brawl on flight to San Francisco after ‘one of them took the other’s seat to get away from another passenger’s constant coughing’

Flight attendants had to break up a fight between two men on a long-haul flight that started after one sat in the other’s seat because he wanted to escape another passenger’s incessant coughing.

The argument started a few hours into the trip from Taiwan to San Francisco when one of the men was angry because a passenger next to him was continuously coughing.

The nameless man took it upon himself to switch seats and went to find an empty space.

He sat down, but a few minutes later the original occupant of the chair returned.

An ensuing argument quickly erupted into a violent brawl and members of the cabin crew had to place themselves between the two men to break up the argument.
