Outstation base reserves fly less than domicile/hub reserves because the only way to get an outstation-based reserve into an assignment is via a dropped trip/sick call or elsewhere with a deadhead. If you were based in PHL (or DCA) you'd almost be guaranteed to fly more. I commuted ORF-PHL last spring on an airplane that had four (yes, FOUR) full deadheading AWAC crews. You can't tell me US Airways likes that.
Hopefully the next few weeks will shed some light on the year to come at AWAC regarding the grievance remedy, a possible fourth domicile, attrition, etc.
Things are stagnant right now and that sucks when you see fast movement elsewhere...but I honestly do think things are on the upswing.
