Ryan Air question
 

So I decided to check it out, bought a ticket long ago.
But I lost the damn confirmation email.

Whats your experience, do they ask for confirmation number at the check-in?

E Ticket

They do, but I expect they can look it up at check-in

Make sure you take photo ID even on a domestic - I was caught out with that

they do yes but they can do a lookup, plus ID yes, no ID is no flight

when I fly with easyjet or ryanair it is normally enough to show a passport.
But I guess you can send them an email with your flight details and your name and ask them to send the confirmation again.
