Seasonal nonstop service from Newark Liberty International Airport to Cyril E. King Airport on United Airlines.
United Airlines operates seasonal nonstop service from Newark Liberty to STT, primarily during peak winter travel season.
Newark gets overlooked. Most New York-area travelers default to JFK for Caribbean routes, but EWR has a quiet advantage: United's hub operation here connects to a massive network across the Midwest, Mountain West, and West Coast. For travelers coming from Chicago, Denver, Houston, or Los Angeles, connecting through Newark to STT is often the most direct itinerary available — sometimes with a single stop and a same-terminal connection.
The EWR–STT nonstop runs roughly 3 hours 35 minutes — comparable to JFK. United operates seasonal winter service, and the airline's MileagePlus program makes this route attractive for frequent flyers accumulating miles on Caribbean travel. When nonstop service isn't running, United connects reliably through Houston Intercontinental (IAH) year-round.
One practical note for EWR travelers: budget your time getting there. The AirTrain from Newark Penn Station is efficient, but the ride from Midtown Manhattan is longer than it looks on a map. Give yourself at least two hours before departure on a busy travel day. On the other end, the arrival into STT is the same no matter where you departed from — a short, beautiful descent over Caribbean water into one of the most welcoming small airports in the region.
