Just checked our November flight with Seaborne and right now it is still a go. STT to SJU.

We do a direct to STT from ROC for the way down with Delta (can't beat leaving ROC at 6 am and being on STT by 12:35 pm) and are using a credit from Seaborne and miles from Southwest to get back via SJU. Timing of flights was the major factor in flying different carriers on the way down and back.
