Ryanair Checked Baggage Each passenger can purchase up to 3 checked bags of 20 kilos. These can be purchased either when making the initial booking or can be added to a booking up to 2 hours before the scheduled flight departure time.

Yes, you can—and absolutely should—buy your luggage allowance before checking in with Ryanair. In fact, you can add checked bags or "Priority & 2 Cabin Bags" to your booking at any time up until two hours before your flight departure via the Ryanair app or website. Buying luggage at the time of booking is the cheapest option, while adding it later (but before check-in) is slightly more expensive. However, the most critical "travel hack" for 2026 is to avoid buying luggage at the airport. If you wait until you are at the check-in desk or the boarding gate to pay for a bag that doesn't fit the "personal item" sizer, the fee can be as high as €70 per bag, compared to roughly €20–€40 online. Once you have checked in for your flight, the app sometimes makes it more difficult to modify your baggage, so it is best to finalize your luggage needs before you hit the "Check-In" button. If you've already checked in and realize you need another bag, you can still usually add it through the "Manage Trip" section, though you may need to re-download your boarding pass to reflect the change.
