This is a very major issue and its been broken since last week. If anyone is trying to use an SWU on AF, you're screwed... same with trying to book BE seats as people have noticed.
I know the "IT" link between DL/AF was not very good before, but come on... now its just totally broken. I wonder who is even working on this or if it has any sense of urgency or priority, or are resources being funneled to work on destroying whats left of the skymiles program to convert it to revenue based earning and redemption.
