Well, I have to admit that this looks like a very nice cabin arrangement. I would try it at the earliest opportunity just to see what they can do - although I'm pretty loyal to BA's Club World.
This type of cabin environment, depending on service, could be very close to the First class service offered on other carriers. I would say Go Envoy upgrades would be substantially more than $500 - airfares overall would rise for these routes. BUT, it looks like they will have a product deserving of higher fares.
Its a good question, the one above referring to award inventory. I would see these being branded an F-type product.
Nice new A330s and a great new cabin - who would guess. Be nice if we saw some rotate to PHX then. I guess we'll see them with NRT service.
