Unlike the other thread going on this topic right now, I can see the YUL-CDG award seats for 1SEP12 on DL.dumb. Of course, I then get the "this flight just sold out" error when trying to select it. However, 7DEC12 IAD-CDG is O9 in EF and will only offer economy on DL.dumb. I'd try calling again, and if they can't see it, ask them to go into the AF/KL system to check for inventory. It's been reported once or twice that excellent agents have done such things when Deltamatic was having one of those days.
