From the beginning
1)777 showed availability of 1 seat. I bought that one seat. At that time .bomb and other sources stated it would be a 777.
1b) My confirmation and those other sources now say it a 767. Presumably, then, I bought the seat that "oversold" the 777 and necessitated an equipment change.
2) I prefer the 777 over the 767
3) I was asking for other FT'ers perceptions about comfort and service on the 767 for transcons. The 767 is an older aircraft, and my opinion is that newer aircraft generally are more comfortable, clean, and unlikely to result in a mechanical.
