Starting from the ground, you climb two flights of access steps to reach
the main deck door. Once inside the craft, you climb a third flight to
reach the upper deck, turn right (usually), pass the galley, heads,
emergency egress door, and enter the flight deck. Variations on the theme
if you're flying the freighter version, but the structure's about the
same. I think it probably qualifies as cabin-class.

If you enter like the passengers, from the jetway, how do you get there?

Even this aside, a little common sense says that a 747 is cabin class,
without having to look at other definitions? g
