When I flew DEN-OGG last month, the plane was changed between the three versions of B777 HD. United sent out seat changes twice. I was excited to see 32 J version (77O) for a few hours, but it was changed to a 28-J version (77M) with a different seat map compared to the original 28-J version (77G).
