Proximity

I don't see long call as something that the pilot group wants or would really be workable with how reserves are utilized. For long call to work, reserve coverage would be even higher than it is today, which is already too high. Also, reserves on long call would be used first, so you'd be assigned anyways. Southwest doesn't use reserves in the traditional sense as insurance. Reserves are used to cover open trips. What would be nice would be true trip ownership, meaning once assigned all protections of a line holder would apply. It would also be good if reserves could select their own trips from open time. Right now reserves are assigned trips somewhat randomly, subverting seniority.
