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".

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.

Load factors by market and direction — St Barths. Source periods differ from the schedule week.

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.

Routes

Every scheduled departure in the reference week, grouped by destination and airline. Seats are estimated; see the methodology for how, and for what "estimated" excludes.
