I booked two tickets departing from the same airport:
One ticket with Airline A, departing at 11:00 to Destination X
One ticket with Airline B, departing at 12:00 to Destination Y
Normally I would fly to Destination X, but there is a chance I may need to cancel that and go to Destination Y at the last moment. Could these bookings be a problem? (I am of course not expecting a refund or anything, I just need to have both options at the day of travel).
Separate of this, can I do the following: check-in for flight A, leave my luggage, go through security, change my mind, get out, request to get my luggage out and check-in for flight B?
