St Kitts ranks 17th overall (33.5) and 12th regionally (49.0). It is a regional connector: it serves 10 Caribbean islands, its largest partner, St Maarten / St Martin (Princess Juliana and Grand Case), takes 22.2% of Caribbean departures, and it has 2,697 Caribbean seats, against 1,528 extra-regional seats.
The Caribbean takes 63.8% of seats and the United States 36.2%. Leading routes are St Maarten / St Martin (Princess Juliana and Grand Case), with 18 departures on Sunrise Airways (S6) and Winair (WM); Anguilla, with 17 departures and 102 seats on FlexFlight (W2); Nevis, with 15 departures and 102 seats on FlexFlight and Cape Air (9K); Antigua, with 9 departures and 870 seats on British Airways (BA) and Sunrise Airways; and Barbados with 8.
American Airlines (AA) is the largest carrier at 28.5% of seats (HHI 1,781), and 33.3% of destinations have two or more airlines. Of its Caribbean seats, 660 are a British Airways leg to Antigua of a flight continuing to London Gatwick (LGW). For 8 of 90 departures, seats were estimated from an airline-level default. In full-year 2025 data, departing flights to the United States were 70.8% 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 | 33.5 | #17 of 28 |
| Regional (Caribbean only) | 49.0 | #12 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 | 12 | 56.5% |
| T100I | Inbound | North America | 12 | 70.8% |
| T100I | Outbound | Caribbean | 12 | 62.9% |
| T100I | Outbound | North America | 12 | 70.8% |
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.
