Right, but what about the milage cost. When I've called to ask about this, the cost to upgrade from Y to W on AF was like 65k miles, the same as what it would take to upgrade from Y to J on delta metal, which is insane. I was going to HUCA but never got around to it.
That's correct. AF considers PE the next cabin, and thus upgrade rewards are really one cabin upgrades on them. Sucks, but that's how it it with AF.
