So can he call up and ask them to deduct additional 23k miles, and than call up to clear the upgrade (there is F availability now)
YES,That is what I did now.
I saw the flight got full,25/26 so I saw my chances are very little.
So I called and she said "I could pay another 22.5k for F and it will cost $100"
So I started arguing to waive the fee,she says don't worry I will wave it,she was ready for me to ask,but they have to try there luck
So did Plan B work? not really, because this seat in first I could have gotten saver without Plan B,but I guess there is a small % that it doesn't go through and I had to be the one,but never mind at least my mother will enjoy the F and not be seated in coach.
