For those that are awarded captain in BI, I understand they’ll be an FO in that base until captain upgrade requirements are met (about a year).

There haven’t been any SFO FOs in BI for the last few months. So for the foreseeable future, will the bottom of the SFO 737 FO list just be new hire captains waiting for upgrade? Seems like a strange situation. Is there that little of a need for FOs in SFO?
