Great base if you can get it. BUT and this is a big BUT you CAN'T. BOH is summer only base with no guarantee of winter flying. The RYR contract crews I believe are getting LTN for this winter. BRK or Storm will take their chances (be very poor). I believe the base only has single figure numbers of based pilots now. If you are thinking of joining FR to get a BOH base forget it. It won't happen. There are lots of people in the company wanting that and consistantly told no chance.
As for roster 5/4 but as the base only has one aircraft and depends on floating Caps and FOs to run if a floater turns up on your weeks work that's no work (pay) for you that week. Bit of a vicious position. No guaranteed work in the winter and indifferent pay in the summer compared to most bases.
