Ryanair's policy would be fair enough if we had a legitimate national photo ID. Note everyone has a driving licence, and many that do have a licence won't necessarily have the photocard type. OK, you can use your passport, but you SHOULDN'T have to carry your passport to travel within your own country. As for student ID, well that's just laughable. Anyone could knock out a student card on their computer. They might as well accept my Blockbuster card.
