Actually, DAM-xBAH has GF, but BAH-SIN has QF number ... the fact that its a transfer rather than a stopover, and that the first segment is on GF, is the thing that both QF and BA reps here pointed to before referring me to GF. Hopefully I can get something from the manager tomorrow.
As for RJ ... the ticket isn't endorrsed for RJ ... was issued before they joined.
Thanks for quick advice!
