They recently did a staffing bid/preference and a lot of people, other than some captains, moved to the base they wanted. Things are very fluid here. For the most part, they try and get you the base you want. TPA is most senior, followed by FLL. FLL shouldn't be too hard to get. As with everything in aviation, timing is everything. Between majors hiring and normal attrition, I wouldn't imagine you having to wait long if you didn't get it initially.
