We fly Deltas AM flight from JFK with final destination being VG.
We arrive around 12:45 and just use the ferry system. Twice we have used water taxis due to extenuating circumstances (covid, snowstorm) but we opt for ferries all the other times. I always have a few plans in place but we like just getting to VG in one day.
I've always felt that coming from NY we are quite lucky. I'm 1.5 hours from JFK and it's a long day but making multiple stops/connections/flights (routing thru San Juan and EIS) just feels like asking for complications. One and done, I say.
