The passenger was travelling from Poland.
A Ryanair passenger who became enraged when he was told he could not claim a scratchcard prize on his flight ate his winning ticket.
The man was flying from Poland to the East Midlands on a Ryanair flight when he won 10,000 euros (£8,765) on a scratchcard he had purchased on board.
Ryanair confirmed he ate his ticket on 26 February after cabin staff refused to pay him the winnings immediately.
The airline said it could not reveal the winner's identity.
Ryanair spokesman Stephen McNamara said the cabin crew and some passengers urged the man not to eat the ticket, but he stood up and ate it anyway.
He said it appears the passenger acted out of frustration and anger.
Mr McNamara explained that all winners must be verified before the cash prizes are handed out.
He said the airline crew did not have the cash "kicking around the aircraft" and the prize had to be collected directly from the scratchcard company.
