Passengers who present printed boarding passes at airports will no longer be accepted to fly with Ryanair, the company has announced.
One of Europe's biggest budget airlines said it was "moving to 100% digital boarding passes" from Wednesday in a bid to speed up travel and lower costs.
It said all customers needed to check in online before arriving at the airport, adding that 90% of its 206 million passengers were already doing so and using digital boarding passes.
Those who fail to check in online ahead of their flight will have to pay an airport check-in fee of up to £55, the airline confirmed.
