Aeroplane passengers should be restricted to two drinks at airports, Ryanair chief executive Michael O’Leary has said.
Mr O’Leary said introducing alcohol limits at airports would help tackle a rise in disorder on flights.
Violent outbursts are occurring weekly due to alcohol, he said, especially when it is mixed with other substances.
“We don’t want to begrudge people having a drink,” he told the Daily Telegraph.
“But we don’t allow people to drink-drive, yet we keep putting them up in aircraft at 33,000ft.”
Crew members and other passengers have become targets, according to Mr O’Leary.
Delays add to the problem, with longer drinking times at airports.
“In the old days, people who drank too much would eventually fall over or fall asleep. But now those passengers are also on tablets and powder,” he added.
“It’s the mix. You get much more aggressive behaviour that becomes very difficult to manage.”
Mr O’Leary said it was difficult for airlines to identify inebriated people at the gate, especially when they boarded in a group.
“As long as they can stand up and shuffle they will get through. Then when the plane takes off, we see the misbehaviour,” he said.
Ryanair staff search bags for alcohol before passengers board flights to Ibiza, one of the worst-affected “party destinations”.
Other challenging destinations include some of the Greek islands.
