I'm going to be doing online check-in this week and wanted to also check-in my parents. They'll be going to the airport separately from us so I was wondering, if I do online check-in at 12:01 am for my parents, can my Dad then go online when he gets up that morning and reprint the boarding passes (that I had already checked in for)? Just in case one of us gets delayed getting to the airport I want him to have his own copies. Is that possible?
