New hires can expect to start in Phenom 300, Legacy 450 or Challenger 300/350 (assigned by company). Quickest Captain upgrade is in in the Phenom 300 which is currently less than 2 years. Its done by SENIORITY.
There is PBS schedule (Preferential Bidding System) along with 8-7 fixed or 7-7 fixed available. Your choice after training. The fixed schedules pay about 30% less than PBS. I don't think many new hires opt for that.
PBS Quick Overview - The schedule consists of 14,15 or 16 work days per 28 day bid period. You bid for 4,5 or 6 day trips. If a pilot has a PBS schedule with 6 days of work, minimum of 4 days off. A pilot with 4 or 5 days of work will have a minimum of 3 days off. These are considered Green lines that the company may assign. Yellow lines of 12,13, 17 or 18 days of work could also be bid . A Yellow line cannot be assigned unless the pilot bids for it.
