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. >I've never seen shuttle busses used to load anything much bigger than a >737 -- airports that use them usually have bridges as well for loading >widebodies and use the busses to load smaller planes.

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. Alan.
