As far as basing goes, all DESO's start on long haul PAX fleet flights and are based in HK until they upgrade to JFO, which at this point bidding for a different base is an option (upgrade is usually around 4 years). ALL DEFO's start off on the freighter fleet and there are a few basing options , if you don't want to live in HK, they can then bid for the PAX fleet after 2-3 years i believe (correct me if i'm wrong on this one).
hope this helps.
