Preliminary studies of A3XX suggest it would be double decked for the
whole length with 10 abreast layout in lower deck and 8/9 (?) on upper.
The 747-600 would be stretched in comparison to 747-400 (dunno if it
includes upper deck), but would retain cross-section.

In Kai Tak (Hong Kong), buses are common for loading/unloading 747s. There
just aren't enough parking bays at the terminal. They have specially built
buses with drivers at both ends, lots of doors on all four sides and mostly
standing room only for passengers. It probably takes about 3-4 of these to
take all the passengers. Its not too bad when loading because passengers do
arrive at the gate at the same time, but when deplaning, they have buses
(oops, almost typed busses :-) ) waiting to collect passengers. Yes, it is
inconvenient, but better than no service at all (since they can't fit any
more planes at the terminal). As for turnaround time, the captain once
remarked "because this plane will be here for several hours, we won't be
parking at the terminal", so I'd imagine if the plane is in a hurry, it'll
get a gate. This may be a commercial decision too, if the gate costs a lot
more than the far away spot. The turnaround time could also be affected by
the slots available.
