St. Croix, the largest of the U.S. Virgin Islands, combines warm Caribbean weather, beaches, coral reefs, historic towns, and a culture shaped by Taíno heritage, African ancestry, European colonial rule, and modern American ties. Travelers arrive through a mix of mainland U.S., Puerto Rico, inter-island, seaplane, and limited international flights. Most use Henry E. Rohlsen Airport (STX), about six miles southwest of Christiansted, while Seaborne’s downtown seaplane service uses a separate terminal in Christiansted. Because Caribbean schedules change by season, always confirm your exact dates with the airline before booking.
Quick Answer
As of July 31, 2026, American, Delta, JetBlue, Cape Air, Seaborne Airlines, Fly The Whale, and limited regional or international operators serve St. Croix. United begins Saturday Newark–St. Croix service on October 31, 2026. Spirit should not be treated as a current option because its flights were canceled in May 2026.
Key Takeaways
- American’s Miami route is the most dependable mainland gateway; Charlotte service is seasonal.
- Delta serves St. Croix nonstop from Atlanta on a seasonal schedule.
- JetBlue, Cape Air, Seaborne, and Fly The Whale provide useful connections through San Juan or St. Thomas.
- United’s Newark route is announced for October 31, 2026, not for travel before that date.
- U.S. citizens do not need a passport for a direct U.S.–USVI trip, but adults still need TSA-accepted identification.
Which Airlines Fly to St. Croix?
The airlines below provide the main scheduled passenger options to St. Croix. A route shown as seasonal may operate only on selected days or during high-demand periods.
| Airline | Main St. Croix routes | What to know |
| American Airlines | Miami (MIA); seasonal Charlotte (CLT) | Usually the broadest mainland connection network through Miami. |
| Delta Air Lines | Atlanta (ATL) | Nonstop service is seasonal, so frequency changes during the year. |
| JetBlue | San Juan (SJU) | Useful for connections from JetBlue’s mainland and Caribbean network. |
| Cape Air | San Juan (SJU) and St. Thomas (STT) | Operates small aircraft and provides frequent regional connections. |
| Seaborne Airlines | Christiansted to Charlotte Amalie, St. Thomas | Uses downtown seaplane terminals rather than STX and STT airports. |
| Fly The Whale | St. Thomas (STT) and San Juan–Isla Grande (SIG) | Puerto Rico flights use SIG, not San Juan’s main SJU airport; allow transfer time. |
| Sky High Dominicana | Santo Domingo (SDQ) | Limited international service; operating days may change. |
| United Airlines | Newark (EWR) | Saturday service begins October 31, 2026. |
Warning: Older travel guides may still list Spirit Airlines from Fort Lauderdale. The U.S. Virgin Islands Department of Tourism says Spirit canceled all flights effective immediately in May 2026, so do not build a current itinerary around that route.
Which Mainland Cities Have Nonstop Flights to St. Croix?
The most useful mainland nonstop gateways are Miami, Charlotte, and Atlanta, but the Charlotte and Atlanta schedules are seasonal. Miami is generally the strongest year-round option. Starting October 31, 2026, United is scheduled to add a Saturday nonstop from Newark.
- Miami (MIA): American Airlines; roughly two and a half to three hours in the air.
- Charlotte (CLT): American Airlines; seasonal service on selected dates.
- Atlanta (ATL): Delta Air Lines; seasonal service with frequency that changes by travel period.
- Newark (EWR): United Airlines; announced to begin October 31, 2026, on Saturdays.
Not every fare displayed from a city is nonstop. Airline booking pages often mix direct and connecting itineraries, so use the “nonstop” filter and confirm the flight number before paying.
St. Croix’s route map is seasonal: the right airline depends as much on your travel date as on your departure city.
Best Connecting Airports for St. Croix
Connect Through Miami
Miami is usually the simplest connection for travelers on American Airlines. It offers broad domestic and international feed into a St. Croix nonstop. When comparing itineraries, leave enough time for a terminal change and for immigration and customs if Miami is your first U.S. arrival from abroad.
Connect Through San Juan
San Juan is valuable for travelers using JetBlue or Cape Air. JetBlue operates between San Juan’s Luis Muñoz Marín International Airport (SJU) and STX. Cape Air also links SJU and STX. A San Juan connection can be faster than backtracking through a mainland hub, especially for travel within the Caribbean.
Connect Through St. Thomas
Cape Air and Fly The Whale connect Henry E. Rohlsen Airport with St. Thomas. Seaborne Airlines provides a separate downtown-to-downtown seaplane trip between Christiansted and Charlotte Amalie. Check the terminal carefully: an itinerary involving Seaborne does not use the same facilities as a standard STX-to-STT airport flight.
Note: Fly The Whale’s Puerto Rico service uses Isla Grande Airport (SIG), which is separate from SJU. Travelers connecting between SIG and SJU need extra ground-transfer time.
Direct Flights Versus Separate-Ticket Connections
A nonstop ticket is usually the lowest-risk option because there is no connection to miss. A single connecting ticket also gives the operating airline responsibility for rebooking when a delay causes a missed onward flight. A traveler starting in Los Angeles, for example, may see one-stop options through Miami or Atlanta and longer two-stop itineraries through another mainland hub. The lowest fare is not always the fastest or safest connection.
Separate tickets through San Juan or St. Thomas may save money or provide better times, but they add risk. You may need to collect and recheck bags, move between terminals or airports, and pay new baggage fees. If the first flight is late, the second airline may treat you as a no-show rather than rebook you for free. Multi-city plans can add a stop in Miami, New York, San Juan, or another gateway, but price the stopover and the St. Croix segment as one complete trip.
Pro Tip: When using separate tickets, choose a long buffer or an overnight stop. Compare the total price after checked-bag, seat-selection, taxi, and hotel costs—not just the first fare shown.
How to Find the Best Airfare to St. Croix
- Search by airport code STX. This prevents confusion with St. Thomas (STT) and the Christiansted seaplane terminal.
- Check both nonstop and one-stop options. Start with Miami, Atlanta, Charlotte, San Juan, and St. Thomas.
- Compare nearby dates. Seasonal routes may operate only once or a few times per week.
- Price the whole itinerary. Include bags, seats, airport transfers, and overnight stays.
- Set fare alerts. Google Flights and other comparison tools can track a route, but complete the purchase on the airline’s official site when practical.
- Verify the schedule again before travel. Caribbean services can change because of demand, weather, or operational limits.
Booking early can help during Christmas, winter holidays, spring break, and major St. Croix events, but there is no single “best” booking day. Flexibility with dates and gateways is usually more valuable than waiting for a rumored weekday sale.
Travel Documents for St. Croix
U.S. Citizens Traveling From the Mainland
St. Croix is part of the U.S. Virgin Islands, so a U.S. citizen traveling directly between the mainland United States and St. Croix does not need a passport. However, adults 18 and older must present identification accepted by the Transportation Security Administration. Since May 7, 2025, a state driver’s license or ID must be REAL ID-compliant unless the traveler uses another accepted document, such as a passport.
A passport is strongly recommended when an itinerary includes a foreign island, such as the British Virgin Islands, because that changes the trip from domestic to international travel.
Non-U.S. Citizens and Travelers From Europe
There are no regular nonstop flights from Europe to St. Croix. Most European itineraries connect through a mainland U.S. airport or San Juan. Travelers must meet U.S. entry or transit requirements, including a valid passport and, when applicable, an approved ESTA or visa. At the first U.S. entry point, allow time for immigration, customs, baggage collection, and rechecking unless the airline confirms a different process.
British Airways, Lufthansa, and other transatlantic airlines can bring travelers to U.S. gateways, but the final St. Croix segment will normally be operated by a U.S. or regional carrier.
About Henry E. Rohlsen Airport
Henry E. Rohlsen Airport is located about six miles southwest of Christiansted. The airport’s code is STX. The terminal is open daily, but airline ticket counters, TSA, and U.S. Customs and Border Protection services may close earlier than the building, so follow your airline’s check-in guidance.
Taxis, rental cars, parking, and passenger pickup are available at the terminal. St. Croix is much larger than St. Thomas or St. John, so a rental car can be useful for travelers planning to visit beaches, historic sites, dive locations, and both Christiansted and Frederiksted. Scheduled air service also supports the island’s tourism economy and local jobs, which is one reason route additions and seasonal cuts matter to residents as well as visitors.
What to Expect After You Arrive
St. Croix is the largest of the U.S. Virgin Islands and had 41,004 residents in the 2020 Census. Its history reflects Indigenous settlement, African ancestry, several European colonial powers, and modern U.S. ties, with the long Danish period leaving an especially visible mark on its architecture. Christiansted and Frederiksted offer waterfront dining, museums, local music and festivals, rum cocktails, fish dishes, and historic sites such as Fort Christiansvaern.
Natural attractions are a major reason to visit. Buck Island Reef National Monument protects coral reefs and includes a marked underwater snorkeling trail. Cane Bay is popular with divers and snorkelers, while Sandy Point National Wildlife Refuge is known for its long beach and protected habitat; seasonal access rules may apply.
What to Pack for St. Croix
Light clothing, sun protection, reef-safe habits, and footwear suitable for wet or uneven ground will cover most island days. These guides can help you choose waterproof sneakers for travel, compare golf travel bags if you are bringing clubs, and select a compact travel razor for your toiletry kit.
Planning is straightforward once you separate mainland nonstop routes from regional connections and check the schedule for your exact dates. With the right gateway, travel documents, connection buffer, and ground-transport plan, you can arrive ready to explore the island’s beaches, reefs, historic towns, food, and cultural traditions.
