Yes, you can add a checked bag or a 10kg cabin bag to your Ryanair booking at any time up until two hours before your flight's scheduled departure. It is highly recommended to do this as early as possible via the Ryanair app or website, as the price for luggage is significantly cheaper when booked in advance compared to paying at the airport desk. In 2026, Ryanair’s "dynamic pricing" means that the cost of adding a bag can increase as the flight date approaches or as the hold reaches capacity. To add a bag, simply log into "My Bookings" on the platform, select your flight, and choose the "Add Extras" option. If you wait until you are at the airport check-in counter, you will be charged a much higher "Gate Bag Fee," which can often exceed the original price of the flight ticket itself. Once added, the bag will be linked to your digital boarding pass, and you can proceed directly to the "Bag Drop" kiosk upon arrival at the terminal.
