I read through several pages and see lots of chatter about trying to select seats for free on a BA flight booked via AA. I couldn’t find my specific situation—sorry if I missed it.

I’m looking to book a cash Economy Basic flight on BA metal via AA (AUS-LHR), and want to pay to select seats now (I’m only an AA Gold, and want to be sure to get the twin seats). If I get my BA PNR, and access Manage my Booking on the BA website, will I be able to pay to select those seats?

I just want to confirm that BA Manage my Booking allows paid seat selection when you booked via AA, and not just elite status seat selection.

Thanks!
