typically two trips a month. about 5 or 6 days each. leave JFK and fly to ANC stay a day or so and then on to HKG stay a day then reverse it all.
Or same thing from LA up through SF or YVR and on to ANC. Sometimes you will only go as far as ANC. You typically will get some A days each month. Available days. 10 hour callout. Seldom used on A days.
