I think the evidence from NWA/Deltaflygirl is pretty compelling DL is aware of and working the problem. If it is IT related or in the domain of one of their JV partners, they probably cannot offer an ETA of how long it will take to solve. Most large companies are understaffed these days and who knows how high AF will prioritize making the fix and whether they will pull employees off revenue-positive work to help give away more tickets.

Also, there is a kind of machismo at work in large corporations, airlines included, that seems to preclude the kind of communication most of us would prefer. An acknowledgment of problems or mistakes, a thank you for understanding, etc. Most big companies I know of are reluctant to even admit their failings internally among employees who are well aware of them.
