Ichkeria writes"It's outrageous for Ryanair to insist on passport ID for travel within the British Isles.
I can't actually find anywhere on their website that states this".
You only need to look at the link I've provided above, Ichkeria! ;-)
Ichkeria also writes "Not that I'd fly with them if they were the last airline on earth"
Why on earth not? They've got a better punctuality record than almost any other European airline. They've lose fewer bags than any other major airline operating from the UK. They've got cheap fares and they've got an honest boss who is prepared to be truthful about the fact that his company exists to make a profit. I've flown with loads of airlines (including full-fare operators, such as Qantas) but I still regard Ryanair as the best airline in the world.
Incidentally, many companies now insist upon seeing a passport for security purposes. If you, as a UK citizen, turn up at an 'easyHotel' within the UK (without a prior booking) you'll be refused accommodation unless you have your passport with you.
