Don’t do that. Either move to a mid-level airline to widen your experience or move up at your regional. Don’t make it look like a small regional shop is not willing to let you move up so, after a couple of years of dispatching, you should be able to move to a sector supervisor or become a trainer/instructor, I know many at regionals that move up after 6months. Especially with all the dispatcher attrition nowadays, don’t let too many new dispatchers jump ahead of you getting promoted at your shop. You will end up interviewing against those dispatchers at the mainline and they will notice that and wonder if there is something about your personality that kept you from moving up while getting skipped by new guys.
