here at RAH, the time it takes to switch bases after your initial assignment (which gives little to no consideration to your preferences) depends on how senior the base you want is. You can have a standing bid on file from day one for the base that you want. As soon as your seniority can hold an opening in that base, you will be awarded it. For example, many of the recent newhires have gone to buffao and left after one month because they wanted STL or CVG, which are pretty junior. For the people holding out for SDF or IND, they will be waiting a few more months.
