The hawaii 777 would never be an option. Besides the fact that I think most of them are no the E/R's, but UA needs to offer a consistent intercontinental C & F class seating. How would they sell the domestic F seating? It just doesn't make sense. (Yeah, yeah, I know the 763 F is not the same as the 777/747 suite F, but it is better than C and still an F product.)

I would have guessed a 763 too though and they'd ramp up to a 777 if demand justified it. They must have a good reason to use a 777--I am not sure what it is though? My guess is either cargo or a lot of high yield F that would demand a suite but that hardly seems likely.
