I'm having exactly the same issue looking for saver awards DFW-LGW, and I'm looking at the end of July 2015, when dates have just become available. This definitely can't be just an oh, they've already sold out already kind of answer. Either they haven't opened AA yet or they aren't going to because they want to hold them back. Really disappointing - this devaluation is really hurting if they aren't releasing nearly the same number of saver as previously.
