This was not my point. A previous poster stated that the time in AB is rewarded as per bonus schemes. Although there is no seniority scheme with regards
to upgrading, there is a waiting list of all the bases with regards to command course allocation once you have been accepted to start the command process. People also can bid for a certain base, hence people can get a quicker command for unpopular bases. On the other hand for popular bases, one can wait for many years. For AB, it is a different story, as it has been acquired as per the deal to receive the slots in SXF, and the commitment to employ AB crew if they apply and pass the recruitment.
