I'm on AA 783 this afternoon. I've been seeing constant tail number changes, I just had a barrage of delays, first to 4pm, then to 1157pm, then to 6am and finally to 7am tomorrow. Clearly, they're not fully back to normal operation.

UPDATE: AA agent said it's due to aircraft maintenance. I'm not sure I believe that as they changed the tail number like 3 times in the last 24 hours, but it is what it is. EXP Agent said he couldn't offer vouches and suggested I go to the airport today and wait in that horrendous customer service line. Hard pass on that...
