The QF suggestion didn't work but I'll remember that for the future.

But just to wrap this up. I called BA.

The BA agent said she could see the BA4461 in the booking but the system wouldn't let her select seats and said she would have to contact the seating team to see if they could - they couldn't either.

She couldn't see anything for the final LCY-DUB and she suggested I call AA to see if there was another confirmation number. But she was puzzled how an AA operated flight on AA flight number was in BA MMB.

When I called AA the agent gave me yet another confirmation number and when I entered it into BA MMB it did regster the last 'missing' flight but also some of the others as well.

The AA site now shows all the selected seats as well.


My MMB looks like a right mess with some seat bookings on one ref and others on the other and some flights on only one ref and others on both.

I'm sure it will all come out in the wash though I'll go to the BA ticket desk at LCY next Wednesday to make sure it's all OK.
