I tried this today for the first time, and it seems like a good idea. Of course i haven't got to the airport yet so i don't know if I'll have any problems, but it seems straight forward enough.

Any one else tried it yet.

Ryan Air? Kowalski recommended it to me and it seemed to work for me last time..

used this system many times and it's great as Ryanair normally let Online Check-in customers on the plane first.If you are travelling with Children you won't be allowed sit in the seats nearest the exit at the back of the plane due to emergency evacuation policy.
Just beware as we were travelling back from East Midlands and the Computer System used by the Airport staff for scaning the Tickets went down.We had to go to the Ryanair ticket desk to get a printed ticket that could be validated by the Security Check-in.Just leave a little time in case of an emergency.

yeah I ve always done on line check in = get priority and cheaper That is if you don t need more than handluggage though
