Adding a AA booking to BA.com
When making a reservation with AA which contains AA and BA operated flights, you can manage seat selection for the AA operated flights on aa.com. However, to do seat selection for the BA operated flights you will need to do that on ba.com using a BA PNR which will be different to your AA one. Unfortunately the BA PNR is not displayed anywhere on AA.com.
Booked as an AA codeshare
If the BA operated flights were booked under an AA codeshare then as long as you added your BAEC number in to the booking on AA.com the BA PNR should appear in you upcoming bookings list after a few minutes. You should be able to select seats for your BA operated flights in it.
Booked under a BA flight number
If the BA flights were booked under a BA flight number even if your BAEC number is entered in AA.com this doesn't appear to get passed to BA and the booking will not appear in your upcoming bookings list on BA.com.
One way to get your BA PNR is
- go to the
Qantas website and put your AA PNR in to MMB
- when in the booking go to the seat selection section and you should see
"Seat selection is only available for flights operated by Qantas. To select seats and manage your booking, visit British Airways site with your booking reference #XXXXX" where XXXXX is your BA PNR
- go to BA.com and look at MMB for XXXXX, the frequent flyer number field will be blank but you can now add your BAEC number and also select seats for the BA operated flights
