I am going to try to get on an earlier flight, will be going standby. Made our reservations for a non-stop in the PM and airline added a new flight in the AM that is also non-stop. Since I booked long ago I can't change without a penalty, reason to try standby. Since the standby flight is early I have to be at the airport at 5:00 am. I will know the night before if I'm going to do this since I will call the airline to find out if there are many seats available. If not I'll stick to my planned flight. Question, if I end up taking the early flight how do I let ME know I've changed flights, do I still use the same luggage tags? Will they know my family needs to get on the bus earlier? Can I make this change the night before since there will be no way to get new vouchers mailed to me? Thanks!
