In the same boat as a few people on this thread. I make monthly trips to BKK and would easily qualify for PQD if I could fly all UA metal... I was happy to fly other *A airlines but it's just too much of a hassle for me to mix match airlines within one itinerary to get enough PQD so I'm trying out the EXP challenge with AA so I can switch to fly CX.... Not something I wanted to do but since I hit 1MM, very little incentive to stick around... Never thought this day would come as UA has always treated me well.
