Ryanair will scrap the paper boarding pass in the next few months.
The company said at the moment eight in 10 passengers use the mobile app for boarding.
Passengers will soon have no option but to use their phones - possibly by April or May next year.
Ryanair Chief Executive, Michael O'Leary admitted he will have to get used to the new system himself.
“I’m one of the last remaining people still showing up with my piece of paper,” he said.
“Everybody who travels with us has the app, the mobile boarding pass is on the app and we’ve got to move more and more people that way.
“It also means, once we get everybody onto the app, nobody will ever again pay for a boarding pass at an airport - the airport check in fee will be gone.
“So, I think it will be a smoother, easier journey for everybody.”
Last month, 19.1 million people flew with Ryanair - a figure 10% higher than in September 2023.
