?? Don't know but I doubt it would be that easy. I have the most experience with AA and they put the reservation on hold for 2 weeks and if not ticketed, it will self destruct! I have booked a return flight knowing it was on the wrong date and then called to change it. Now that the airlines are charging for everything, there's probably a fee involved but in the past if you were on Biz ticket there was no fee.
