The 175 has only been offered to new hires since the initial cadre of FOs. I got lucky and caught the wave early, I'm about 85 from the top on the list of 175 FOs in DFW. We had 82 hard lines for October, and I'm assuming some of the pilots ahead of me either forgot to bid or bid reserve to get the days off they wanted. The initial cadre are due for upgrade soon, so there should be some movement upwards in the near future. We should be looking at somewhere around 200 FOs on the 175 to staff the full boat of 40 planes that comprise the initial order. The CRJ and 145 have much more senior FO lists as they are existing rather than new fleets. FOs can only change fleets when displaced or when they upgrade to CA, per the CBA.
