Thanks all for the responses. I was automatically rebooked on the same DFW-HKG flight for today. Apparently there was nothing else available, via LAX, SFO, ORD, EWR. There was something via YVR but would have gotten me to HKG later than the direct one today. I called the PLT line 5 times and got the same reply every time. One agent was even willing to put me in J or F for AA metal but sadly nothing was available. I asked if they could put me in J for CX but got shot down (worth a try right?). I did ask at the AC but it was the same story. At least they gave me a hotel voucher and an MCE seat. Oh well. Do you think I should get some compensation (either miles or credit)?
By the way, this was an award ticket.
