VX legacy seem to shift additional capacity to FLL-SFO/LAX in the winter time when demand in other markets like BOS-SFO/LAX drop. I assume that's because demand in FLL markets stay around stable all year. And this is more of a utilization play. I guess they could keep doing that. But reality is the yields have been horrible since mint entered and that won't change. Based on how well they are doing on FLL routes, there is a very good chance B6 would add to FLL-SFO/LAX. Which would not only kill any kind of seasonal play for AS, but also probably cause AS to drop FLL-LAX.
