The Route: London → Sint Maarten → St Barts
There are no direct flights from London to St. Barts. The journey requires a connection through either Paris (CDG) or a North American hub (New York, Miami, Atlanta). The fastest and most popular route for UK travelers is via Paris on Air France, though transatlantic connections through the US are often cheaper and sometimes faster depending on timing.
Option 1: Via Paris (CDG) — The French Route
Air France connects London Heathrow (LHR) to Paris Charles de Gaulle (CDG), where they operate direct long-haul service to Sint Maarten (SXM). The connection in Paris can be smooth if timed correctly — CDG is large but well-connected. Total journey time: approximately 10–12 hours. Fares: €600–€1,600 return in peak season.
The advantage of this route is that you arrive on a single airline (Air France throughout), with luggage checked through, and a booking experience that is more coherent. The Paris connection is also convenient for UK travelers who want to spend a night in Paris before or after St. Barts — a popular combination.
Option 2: Via New York or Miami — Often Cheaper
Flying London to New York (JFK/EWR) or Miami (MIA), then connecting to Sint Maarten (SXM), can be significantly cheaper than the Air France Paris route. The trade-off is a longer total journey (12–16 hours) and two separate booking legs. American, Delta, United, and British Airways all serve the transatlantic leg.

A popular approach for UK travelers: fly London to Paris, spend a night in Paris, then take the morning Air France direct to SXM. You arrive in Sint Maarten in the afternoon, connect to St. Barts, and begin your Caribbean holiday well-rested. The reverse works equally well on the return.
Step 2: Sint Maarten to St Barts
From SXM, the inter-island flight to SBH with Winair or St. Barth Commuter takes 10 minutes and costs €100–€300 round trip. The ferry from Sint Maarten to Gustavia takes 45–60 minutes and costs €60–€80 round trip. Both require advance booking from December through April.

What to Know Before You Go
- St. Barts is a French collectivity — UK citizens need a passport (not just an EU ID), which you’ll have post-Brexit anyway
- Currency is the euro — bring or exchange before arrival
- Inter-island luggage limit: 10–15kg — pack light
- Book your rental car before you leave London — the island’s fleet is small and peak-season availability sells out
