Every passenger is allowed 1 checked bag, which must weigh less than 20kg. Passengers must ensure they adhere to this weight restriction, as exceeding it will incur an additional fee. It is also important to be mindful of the size limits placed on a checked bag, as Ryanair will not accept bags larger than 81x119x119cm.

Ryanair is notorious in 2026 for being exceptionally strict with baggage allowances, as their business model relies heavily on ancillary fees. Every passenger is allowed one "Small Cabin Bag" (maximum 40x30x20cm) for free, which must fit entirely under the seat in front. At the boarding gate, staff frequently use metal "sizers" to check bags; if your bag is even slightly too large or does not slide into the sizer easily, you will be charged an "Airport Bag Fee," which can be as high as €45 to €70 depending on the route. If you wish to bring a standard carry-on suitcase (up to 10kg and 55x40x20cm), you must purchase "Priority & 2 Cabin Bags" in advance. Staff are particularly vigilant about "soft" bags that look overstuffed and "hard" shell cases that cannot be compressed. Furthermore, Ryanair only allows one piece of luggage per person; if you have a small handbag or laptop bag in addition to your free cabin bag, they may insist you "consolidate" them into one bag or pay for an extra item. To avoid stress, it is best to measure your bag at home and assume the gate agents will check it.
