Had a 3.5 to 3.75 NM taxi to parking at ZBAA last year. Took about 12 min behind a follow me vehicle.

Probably about the same distance taxiing out to 14L at ORD via the route through the hangars on the north side of the field.

Longest taxi out was probably about 2:00 at ORD via the route above.

Longest taxi in from runway to gate was about 6:15 at LGA back in 2001 when there were no slot restrictions so we ended up with a huge mess. We landed and had no gate and without an ORD style "penalty box" to wait in, we had to continually circle the field waiting to get in.

Longest time on the plane with passengers (on ground after boarding) waiting to depart was about 7:15 at ZBAA waiting to depart last year.
