Which document must all passengers present at Ryanair check-in?

All passengers checking in with Ryanair must present a valid government-issued photo ID or passport. This requirement is in place to ensure that the identity of each traveler is verified for security purposes, in compliance with international travel regulations. A government-issued identification serves as a primary means of confirming a passenger's identity, which is crucial for boarding a flight.

While the boarding pass is also necessary for the boarding process, it is typically issued after check-in and does not serve as an identification document. An airline membership card or a printed itinerary may contain some travel details but do not fulfill the requirement for identity verification. Therefore, the necessity of a valid government-issued photo ID or passport for check-in is critical to maintaining security protocols and ensuring safe travel for everyone involved.
