Yes, checking in online is mandatory with Ryanair in 2026 if you want to avoid significant fees. Online check-in opens 60 days before departure for those who purchased a seat, or 24 hours before for those with a random seat. If you fail to check in online at least 2 hours before your flight, you will be charged an airport check-in fee (typically around £/€55). Furthermore, Ryanair has moved to 100% Digital Boarding Passes via their app; they no longer accept printed passes at most airports. If you arrive at the airport without having checked in, you must pay the fee to have the staff process your boarding. A unique exception remains for flights from Morocco, where you must check in online but still present your digital pass at a desk to receive a physical printed document per local regulations.
