shrimper,

There's nothing I can think of. As long as you don't need to cancel your flights for any reason, there's no down sides to online checkin 3-4 weeks in advance of flights. Just don't lose your boarding cards! I'll be checking in online on Thursday when it opens for my next flights. It doesn't really save much time if you also have to check luggage in, but means you know you're all sorted before you get to the airport.

Thanks for the reply Dazbo, I feel sure most of us would never want to cancel a flight but problems do some times come along, just out of interest what would happen if I had checked in?
