LAX based guys fly through Vancouver to Anchorage, or direct to ANC or sometimes through SFO to ANC. You'll then spend a day (or 2-3) in ANC before heading to HKG. From there, you will generally spend a day or 2 before heading back to ANC, further day and then back to LAX.
ORD based guys will fly direct to ANC, and the rest is as above except you'll finish flying back to ORD or JFK. You will also probably start quite a few of your patterns out of JFK and then fly JFK-ORD-ANC through the night.
JFK based will do JFK-ORD-ANC etc.
Plenty of variables, but that is the basic idea.
Bottom line is......lots of time in ANC and HKG.
Patterns can be as quick as 5 days or sometimes blow out to 10-11 days depending on whether your roster has you spending lots of time on the gnd in either ANC or HKG (time in HKG can be for sims, courses or just nothing), and whether you do a couple hops between ANC and HKG before heading home.
