Thanks clubman. I've tried that but it is only for changing your actual flight not the other options like Priority Boarding and on-line check in. I'll just have to mill with the throngs in the airport on saturday morning.
Go to 'change flight details' get phone no. for Ireland, it is a premium rate (1.75per min I think) and they will add on-line check in for you. Did this myself this week and was all sorted within minutes. Well worth it to avoid the queue in Dublin airport.
Thanks for that Fickle. I found the number and paid the fee. Still don't have access to on-line check in though. How did it work for you? Maybe their system hasn't updated yet.
I am not travelling until next month, however when I phoned I was assured that priority was added and I received an updated email with my details. When are you travelling? on-line check in is available from 2 days to 4 hours before flight. Hope you are sorted.
