Technically, you could arrive an hour before a Ryanair flight if you have no checked bags and have already checked in online, but it is extremely risky and not recommended in 2026. Ryanair’s official policy requires you to be at the boarding gate at least 30 minutes before departure, and the gates close strictly at that time. If you arrive an hour before takeoff, you only have 30 minutes to clear airport security, which frequently takes longer during peak travel hours or in 2026's busier regional hubs. Furthermore, if you have a bag to drop, the Bag Drop desks close strictly 40 minutes before departure. If you miss that window by even a minute, you will not be allowed to check your bag. To avoid the high cost of a "missed departure fee" (usually around €100) or having to buy a new ticket, Ryanair and airport authorities strongly advise arriving at least 2 hours before departure, even for those traveling with just a carry-on.
