Not sure if this should be here or an BA forum since its ticketed by BA even though it is AA metal but since this thread is already open, there is lots going on with AA plane swaps lately and BA ticket is not keeping up.

Example I have a BA ticketed flight which LHR-JFK-MIA are in AA metal in a month or so. LHR-JFK plane have been swapped now from 777-300 to 700-200 and our row 4 seats have changed to row 1 seats without any information whatsoever. It also looks like this is the plane where seats alternate looking forward and backward and row is is backward looking. Going to wait patiently to check in time and see what plane it shows by then and see what seats are available.

The JFK-MIA flight have been changed 3? times already. First it went from 737-MAX to 737-800 to different 737-800 and ofcourse seat maps are not alike so the current BA seats I have ticketed are not even available on current plane. AA have changed my seats there as well although looking at SeatGuru it is a wrong plane/layout currently in AA site as well. The flight time also changed 2h later and then 1-2h later again and I called BA&AA and end result was that I was back on my original timing?!? altough they tried to offer me a seat on plane that leaves hour before I land from LHR which I had to remind them. Then they were, ok this is next available is that ok and I said yes, it is what I originally had but which you told was canceled and for that reason I was moved 2h later but if it is back in rotation then yes, I am happy with that connection... oh and I cant change seats to those AA flights in BA site as the transfer doesnt work (it doesnt recognize BA number) and I cant change JFK-MIA seats as I have actually it twice in AA site, same time with 2 different seat assignments :P

Seems AA is bit like TK. You know what plane you have when you board it.

I have tried to adjust my business class expectations to really low but I am pretty sure I will be disappointed still. Thats what flying QR business does for you I suppose.
