If you are familiar with the bureaucracy of any big corporation, you know that any announcements of changes and wishful thinking do not matter at all, even coming from CEO.
Any vision has to follow through all the interfacing meetings and even more meetings about meetings fighting for priorities without actually doing anything to solve the problem.
Only then the teams can peak up any tasks that have substance.
The real deadline is December 31, when the status counting resets for the next year. I do not expect Delta to announce anything concrete until beginning of December. Yes, it is bad for planning our travel, but it is simply unrealistic even for an innovative hi-tech corporation, let alone an old school giant like Delta or Bank of America.
Things move as slow there as in any state department.
