The flight ex-DFW ended up canceling - good looking out

So in some cases it is not a bug but a feature to not allow people to buy tickets..
Anyway couple of days ago my colleague was trying to buy himself last minute one way ticket on TATL flight, but the very same problem. He was in US and was trying to use MC card issued by European bank and ended up calling the agent instead. Crazy that such a problem last for more than 3 months and who knows how long it was there before.
