When attempting to burn a last batch of A+ credits on a business class upgrade, I called midnight the day prior in order request if any business class upgrades were available. Unfortunately, the AirTran call center is now operating at reduced hours, specifically, between 7 am and 7 pm eastern. I seem to recall them being open later previously, but I don't recall the exact time window.

Am I correct that the hours have been reduced (presumably as part of the cessation of the AirTran A+ rewards program / conversion to WN), or was it always this way?
