GMJ
Pay is less than XOJ since the schedule is easier. The schedule is dictated by the customer (Silicon Valley Fortune 100 company). It's easy enough to figure out who it is if you don't already know.
Schedule is M-F, no weekends, no overnights (unless something breaks). Shuttles run to and between HIO MHR SJC and IWA. SJC is not a base .. has been discussed in the past but the customer does not want to bear the high cost of setting up there, even though the majority of the traffic moves through SJC.
A typical day might be leaving MHR or HIO at 0730, going to SJC, continuing to IWA arriving later morning. Shuttles run in the opposite direction from IWA. Hang out there until 1600-1730 or so, and reverse the route. You always start and finish at your base. Home every night.
All holidays are off. There is no flying over Thanksgiving week, nor the two weeks of Christmas and New Years. It's a standard Silicon Valley high tech schedule.
There are a lot of homesteaders at GMJ; upgrading is luck of the draw as people leave above you.
