Great if that is the case but are you sure that is First and not just an 'old CO' aircraft with their usual business class config? What routes and flight numbers are you referring to here?

Edit: Just checking some routes w definite 'old UA' metal in ANA - none of them show any availability in F - and surprise, surprise, all of a sudden has a 'business cabin'. So I it is indeed - very good news for those 12th hr redemptions!
