Thanks Jason - I already changed my arrival (12/3) flights (had booked two one way routes instead of a RT) with Delta via SJU and Silver. I was working on re configuring my return (original flight out of STT but want to be safe in case the seaports aren't open) looking at Air Sunshine as their timetable worked best and we are private pilots so like the smaller planes. You could not book a one way return out of EIS so we called them - that is the response they gave so who knows what is going on. It shocked me so wanted to fact check here.
