I had the same problem trying to book ticket to Madrid via DFW for Nov. 2011. Which is way after the DEQM ends. I called the EXP desk and was told to use multiple cities, did that and got the ticket, but at a higher price. That same route is still listed online today and then when you try to make the reservation you get the message fare no longer available. Still available using multiple cities, Is AA trying to make more money?
