The point of having one huge multi-class bid with class dates all the way out through May was to prevent the company from having to do multiple realignments, displacements, and vacancies in succession with all the reductions in flying that were going to happen. 11-09 has covered (supposedly) all training and staffing needs through May, thus there shouldn't be another vacancy till around that time. I don't even know if they are allowed to do another vacancy posting with class dates that would start before the class dates from 11-09.
