I have a somewhat different but serious question.
My company wants us buying F fares on AA,(fully refundable F) especially when flying in a country outside of our companies HQ’s. I just had a problem where my wife’s father passed away, and I was two hours from departure when I got the call from her that we had to go to the funeral. So I quickly called AA and moved the flight to another day knowing I will use it in the future, so I rebooked the ticket at an approximate time I may or may not use on that day. More than likely I will need to change the date again. So...
How many times can I change an F fare on AA? How many times can I check-in, use the lounge, and not fly before the airline penalizes me? Will there ever be a case where the airline will not refund the ticket? Or blacklists me?
