Our on-line check in is coming up. Do I have to wait until midnight EST to start any of the process? Or once our trip is paid in full, will I be able to start completing the forms before the actual check-in date? I don't know what's all involved, but I know that the PAT section isn't until page 5 or 6 somewhere, so wondering if I can do any preliminary stuff beforehand (once I PIF). I know I can't make any reservations etc, but if there is demographic info I can have done ahead of time, I'll do it. Thanks
