Something else transpired and they asked him what seats he wanted and at that point, his phone disconnected. He assumed no change had actually been made so didn’t check further. But AA claims “We've done an extensive review of your booking. The change of date from Oct 04 to Oct 07 was done upon your call-in request made on Oct 02”. At least that is what I garnered from the Twitter exchange he posted. It seems a case of miscommunication and misunderstanding.
