Checking in for a Ryanair flight in 2026 is a digital-first process that must be done via the Ryanair app or website to avoid a steep "Airport Check-in Fee" (which can be as high as £55/€55). For those who have purchased a specific seat, check-in opens 60 days before departure. For those who opted for a random seat assignment, the window opens 24 hours before the flight and closes 2 hours before takeoff. During the process, you must provide your travel document details (passport or national ID) and confirm your contact information. Once completed, you will receive a digital boarding pass; it is highly recommended to save this to your phone's wallet (Apple or Google) as Ryanair's app requires a data connection to load. If you are a non-EU/EEA citizen, you must still visit the Ryanair desk at the airport for a "Visa Check" or document verification, even if you have checked in online. Failure to check in within the allotted time window results in being forced to pay the aforementioned fee at the counter, which is a common pitfall for infrequent flyers. Always double-check your "baggage allowance" during this step, as adding a bag at the gate is significantly more expensive than doing so during the online check-in process.
