I wonder if you not receiving those change notices was due to some email settings that was sent to spam by mistake.
Nope, checked all of that. When I made a change to my settings (adding yet another email address) I was promptly notified and I also received emaill notification when the ticket was purchased. I have every possibly notification (email, text and phone) set up and got nothing. Just like with the first major schedule change 2 weeks after purchasing the ticket.
I fly out of Dayton, they use a regional jet to CLT and then either a 737-800, 757-200 of an Airbus to SXM. I do not believe AA uses the 737 MAX for the SXM route but I am not 100% sure. The agent stated it was due to moving aircraft around to cover for where the 737 MAX was used.
I would expect more major shceudle changes with any airline that uses the 737 MAX.
