Just got a notification from AA that our flight time had changed (by a big TWO MINUTES! ) but they also changed our plane from a 737 (never was a 737 max..) to an Airbus 319. Since our flight had not been that full, I suspect they have cancelled some non-stops, like Charlotte and made them connecting through Miami.
Everything was there when I logged in today, with the changed flights. They changed our seats also, so I went in and changed the seats from what they had assigned. Our Miami flight down was pretty empty and now it is virtually full, so I think they must have consolidated some flights for then.
Mine still shows the Max 8 on return but email showed the Airbus and an hour longer layover in MIA. Not a big deal as long as I get home. Retuning on Friday so if for some reason they cancel or bump me to next day i have my condo through Sat.
