This morning I received a PHONE CALL from AA about a June reservation I have to Panama. I had checked the reservation recently, and it had been changed. On one leg, they had me departing before I arrived! My Panama trip has been rescheduled to April 2021, but AA doesn't yet have their schedule open for the return part of the trip. The agent was calling to see if I was aware of the change and wanted to cancel or reschedule. I explained that I was just waiting for their calendar to open up for the return portion and I would then reschedule. I thanked her for her call. I was amazed - great customer service!
