All Ryanair flights from all airports.
If the airport does not have a dedicated "document check" desk, you must get the boarding pass stamped at a check-in desk.
The "document check" is where they will check if you are admissible to the destination country with your passport and whether you need a visa (and check you have it, if you do).
