Forgive me if I'm wrong, but RYR make up their on rules which may not be in line with EU laws. For example, on internal flights, RYR insist on a passport being presented, not a local government ID card.
Or a non-EU passport holder in possession of a perfectly legal visa, will be denied boarding unless its been stamped.
RYR bend many rules, people who live in glass houses and all that.....
Please point out the EU law that FR is in breach of with respect to Passports........
