To fly with Ryanair in 2026, the primary documents required are a valid passport or a National Identity Card (for EU/EEA citizens). It is crucial to note that Ryanair does not accept driver’s licenses or birth certificates as valid travel identification for any flight. As of late 2025, Ryanair has implemented a mandatory online check-in process that must be completed via their app or website at least 2 hours before departure. During this process, non-EU/EEA passengers are often required to complete a "Visa Documentation Verification" or "Passport Verification" through the myRyanair app; failure to do this digitally may require you to visit the airport check-in desk for a manual document stamp before passing through security. If you are traveling internationally, your passport should typically have at least 6 months of validity remaining from your date of entry. Additionally, you must be able to present your digital or printed boarding pass at the gate. If you fail to check in online or arrive at the airport without your documents verified as required by the app, you may face significant "Boarding Pass Reissue" or "Airport Check-in" fees.
