Basically the bid is designed, in theory, to place new hires across virtually all the bases and thus avoid a shuffle later after they are on the property to position the staffing for summer '16 flying.

My guess: the majority of the "unfilled vacancies" in this bid after the dust settles, and thus actually available to new hires in upcoming classes, will largely be the same bases and seats that always go junior.

Personally, I'm not anticipating too many unfilled vacancies in DEN, for example.
