For most Ryanair flights in 2026, the online check-in window closes strictly two hours before the scheduled departure time. If you have not checked in by this point, you will likely be forced to pay a steep airport check-in fee, which can be around €55 or £55 per person. The time the window opens depends on whether you have purchased a seat. If you have paid for seat selection, you can check in up to 60 days in advance. If you opt for the free random seat assignment, the window only opens 24 hours before your flight. It is also important to note that as of late 2025, Ryanair has moved toward a "paperless" system; while they still accept printed passes in specific regions like Morocco or Turkey, most travelers are now required to use the digital boarding pass via the Ryanair app to avoid additional handling fees at the airport gate.
