And I ask yet again, how would a layperson realize this combination is invalid amongst the many other options QF may have presented such as BA or IB? The pricing doesn’t seem off. The flights don’t seem to be off. The only red flag would be arriving at a bus terminal but as mentioned earlier that’s not unusual for travel in the US. And I ask what specifically makes taking a bus connection invalid? It seems to me that QF was unwilling to ticket what is a legitimate itinerary despite displaying the option, taking the points and the taxes and fees to process the booking.
At a minimum, the OP should escalate this with the award booking team QF set up specifically for these ongoing issues with QF awards and I would be surprised if QF couldn’t make this right one way or another at no extra cost to the OP. Surely, QF could book BA flights to get them to AUH without much of a fuss given their partnership? Even if saver space isn’t available, I would be surprised if QF doesn’t have a special arrangement with BA and other OneWorld partners setup for IRROPs and these events!
