UA 223 supposed to operate w/a 757 on 22 Apr.
Overnight it was changed to a 777 (N777UA arriving from IAD).
Seat assignments were changed to reflect the new equipment.
Just checked to see if seats had changed reflecting an upgrade and indeed they were, but then viewed seat map and back to 757.

So, all the original 757 seat assignments are out the window and people have been changed to 777 seats and now new 757 seats. Annoying, yes. And just nuts really, operationally. Why did the equipment change? Why did it change back?

I have not had ONE trip this year that didn't have some IRROP or processing issues. My corporate status match program with DL and AA just got a lot more appealing.
