It's a short escalator ride from the AC to the boarding area, in the sattelite but allow some extra time from security to the AC. There is a set of stairs up and over and down that needs to be negotiated halfway in between. I haven't seen an elevator or an alternate route (haven't looked).

Also, I have been advised by FA's on several occaisions, inbound, to try and hold onto my fast pass card going through Immigration to use for my return. Never had a problem, so I have a spare or two. Just sayin'.
