Thanks!!

I was able to pull up the "operated by BA" segments LHR-FRA and FRA-LHR to select seats ^!

So now that I've selected seats, I'm worried about whether or not this will affect my waitlisted upgrade for the outbound AA flights ... it appears from the post immediately prior to this one that it will not, but if anyone has experience with this I'd appreciate your thoughts.

Incidentally, I picked seat 9C on the A320 for LHR-FRA and 8C on the A319 for FRA-LHR--any thoughts on whether this is a good choice?

Also, is there a SeatGuru.com or SeatExpert.com equivalent that lists equipment and seats for BA and other European carriers?

TIA!

cheers!
