I recently had the following problem with two award tickets on the same routing. I had an AA award ticket LAX-MIA-LHR and a QR award ticket LHR- DOH, with 4 hours connection time in LHR. Luggage was checked through from LAX to DOH, had a bp issued by QR in addition to the AA bp. Alas, the AA MIA-LHR fight was delayed for 4 hours due to a technical problem that involved swapping planes. Since I would not make the QR flight, I talked to an AA agent while on the ground in MIA and she said that she had booked me on a later QR flight. I arrived T3 in LHR, transferred to T4, then talked to a QR representative at the transfer desk to verify my reservation on the later QR flight. I was told I was not booked on that flight, but was booked on an earlier flight -- but the boarding for that flight was already closed. Then I was told that QR would not book me a later flight and was told to go back to AA in T3 to talk to them. I did, and had an extremely helpful AA agent who was surprised that QR would not accept the AA request to book me on a later QR flight. She talked to the QR folks, reminded them that under Oneworld, all Oneworld carriers were supposed to honor even back-to-back tickets as if they had been made on a single ticket. QR said that because I had an Award ticket, I could not change my flight to a later time according to their rules. The AA agent pointed out that this was in violation of the spirit, if not the letter of the Oneworld alliance. The long and short was that QR refused to book me on a later flight and so the AA agent then booked me on a BA flight leaving the following morning to DOH and provided vouchers for the overnight stay. As it happens the AA agent was also the AA representative to Oneworld and said she would take up this problem at the next Oneworld meeting since it was in violation of Oneworld procedures. It was clear from the AA agent that all Oneworld airlines are supposed to recognize back-to-back tickets, when both tickets are on Oneworld flights, as if they had been booked on a single ticket, whether paid tickets or award tickets. This appears to be an agreement among the Oneworld airlines, not a specific rule, which (I was told) was why QR insisted on following it's own rules rather than the aged-upon policy among the Oneworld airlines. As the AA agent said, QR is new to the Oneworld alliance and hasn't fully understood the procedures that are to be followed. Hopefully this will be sorted out at the next meeting of the Oneworld airline representatives -- in the meatime, I thank the AA agent for her help in sorting out the problem with QR by arranging for me to fly out on BA on their next flight to DOH, the following morning.
