St Lucia ranks 14th overall (38.9) and 17th regionally (42.8). It is a regional connector, close to the threshold on two tests: it serves 8 Caribbean islands, against the 7 required, and its largest partner, Barbados, takes 45.1% of its Caribbean departures, against a limit of 50.0%. It has 2,574 Caribbean seats and 6,371 extra-regional seats.
Hewanorra accounts for 46 departures and 6,611 seats (73.9%); George F. L. Charles, Castries, for 43 departures and 2,334 seats (26.1%).
The United States takes 65.9% of seats, the Caribbean 28.8% and Canada 5.4%. Leading routes are Barbados, with 23 departures on Caribbean Airlines (BW) and interCaribbean (JY); Miami (MIA), with 14 departures and 2,359 seats on American Airlines (AA); and Atlanta (ATL), New York (JFK) and Trinidad with 7 departures each, on Delta Air Lines (DL), JetBlue (B6) and Caribbean Airlines respectively.
American Airlines is the largest carrier at 35.4% of seats (HHI 1,972), and 26.7% of destinations have two or more airlines. In full-year 2025 data, departing flights to the United States were 84.0% full.
Score and rank
The connectivity score is an index on 0–100 built from departures, destinations, airlines, hub links and seats; the regional score uses the Caribbean subset only. Both are defined in the methodology. Not a percentage — an island does not have "96% connectivity".
| Measure | Score | Rank |
|---|---|---|
| Overall | 38.9 | #14 of 28 |
| Regional (Caribbean only) | 42.8 | #17 of 28 |

Load factors
Actual passengers against actual seats, from Eurostat (2024) and BTS T-100 (2025). Monthly and historical: these do not describe the reference week. Route-months the source reports inconsistently are excluded, so every figure here is publishable.
| Source | Direction | Market | Months | Load factor |
|---|---|---|---|---|
| T100I | Inbound | Caribbean | 2 | 71.3% |
| T100I | Inbound | North America | 12 | 84.1% |
| T100I | Outbound | North America | 12 | 84.0% |
Low season against peak
Peak week pending. This edition measures the week of 19 October 2026 only, and that week is an early shoulder week rather than the bottom of the season — some winter services start in October and others in November and December. The peak week is collected separately, and no low-versus-peak comparison is shown until it exists.
