SJU is almost fully staffed, mostly people from the region. They only have 1900s and 99s. From what I gather, there aren't too many people who have been interested in moving down there, anyway.

Billings would be an easier base than SLC- Salt Lake has been rather popular lately.

Schedules for 99s generally run 5 days a week, with many runs having a Saturday morning flight for outbound cargo. No Sunday flights.
