CHAOS broke out on a flight from Malta to Stansted as passengers were forced to separate two brawling men.
The two Ryanair passengers were in an altercation about seats, after one refused to let the other pass through the aisle.
A witness said: "The British man wouldn't let the American man pass through to get to his window seat and then some words and swears were exchanged before a scuffle broke.
"The flight was delayed two hours - everyone was annoyed."
The men can be seen swinging at each other while shocked passengers look on, before intervening.
Passengers could be heard moaning: "We'll never get home."
Members of staff also were forced to separate the two passengers to stop the violence.
Ryanair said in a statement: "Two passengers on this flight from Malta to Stansted (3 July) became disruptive ahead of take-off. Cabin crew diffused the situation before the aircraft departed safely for Stansted following a minor delay."
