I am flying MSP-PHX on DL in late January and noticed this week that the aircraft for that flight on the app has changed from a 757 to an A330. This would be a pretty significant aircraft change, however the seat map still appears to be the one for the 757. Is this likely a glitch or does it normally take awhile for the seat map to update? I’m really hoping this change is real but it is pretty close in at this point so it seemed odd. Thanks!
