I used this fare 3 or 4 times per year since I moved to BKK, as the fare difference (AA) BKK-HKG-LAX in coach (use SWUs to UPG,) vs. HKG-LAX makes this a winner and I don't have to deal with a CX coach flight in their 20 across (OK, exaggeration, it's only 16 across,) that either doesn't earn AA RDM's or is a terribly long connection. Doing this next week and an easy way to build in a stopover in HKG.
Each one I've done has been the A330-300 with lie flats. Very nice.
Did the bidding thing once; it's comes out the same as the I fare without all the last minute hassles.
