UPDATE 2: Just to add. Broke down and called BA.
1) When I asked to confirm that my AA FF was in the system, he said it was NOT and asked that I provide it. NOW I entered this information when I did the booking... how would he not see this? Possible?
2) When I asked if my Platinum status was visible, he answered yes.
3) When I asked about seat availability in the UD, he stated exactly what I was seeing on BA.com, only 60B and 63A. He then says, that if I want that seat, I would have to pay USD$122, I then told him that I had already paid for the seat I had 63A.
4) I asked him about the bassinet seat in 64A. He said that it was still showing as available, but that it was being held. I asked when it might become available and he said something like 24 hours prior, but that I might be bumped for a parent travelling with a kiddo.
So... there you have it... one anecdotal reference regarding Platinum/Sapphire saga and seat selection.
Am I missing something? Here is the expertflyer snapshot...
Thanks again folks.
