I have eight active bookings currently on British Airways, and have recently been informed that I will be transferred to the United States in July 2024. I have an American Airlines AAdvantage number, and would like to switch my current bookings (all of which were done on the BA website) to American Airlines.

I see no way to do this online.... or is there a way? Avios will be of little use to me a year from now.

Thanks for any advice.
