United has three versions of the 747-400, designated OP, OB and OA. The passenger capacities are, respectively 301, 372, and 418.

I seem to get either an OP or an OB when I fly Pacific routes into NRT or HKG. Does anyone know where the OA is deployed?

I would want to avoid the OA, as it has an extraordinarily dense Business Class seating configuration, with 40 Business Class seats upstairs, where they fit only 30 in the OP or OA. Perhaps it is for Hawaii service?

There is also the two class 747-100, with 450 seats, but I understand that is for Hawaii only, and not the international routes.
