The budget airline boss was feeling generous!
It's safe to say that Ryanair don't often give away things for free, so passengers on board a flight to Dublin from Liverpool on Saturday were surprised to receive a treat.
The flight was delayed by none other than Michael O'Leary himself and jockey Davy Russell, who were returning to Ireland after winning the Grand National.
Davy claimed a dramatic victory at Aintree riding Michael's horse Tiger Roll.
There was no private jet organised for the thrifty two as they boarded the plane ten minutes after the scheduled departure time.
Passengers got a shock as Michael took to the PA system to explain the delay.

He then offered his fellow passengers a free bar paid for by him. But there was a catch - just one drink per passenger.
Never change Michael, never change!
