in the meantime, back to topic maybe:

I have sometimes found that if you play it right and time it right and plan it well, you could book a RT award whereas the other half is something you dont want to fly but you could try to control some aspects of it. You can try to get bumped on the return, which you had no real intent or hope to fly on anyway... You could end up with something for it, and essentially do what you wanted from the outset, which is to have a one way award, except for the extra trip to the airport and back home to take care of the bump. Definitely worth a shot! most likely a huge risk. I might plan a cheap MR for my return if I did this.
