Excellent job Thomas! It definitely requires time and energy to gather this data.
If one can accept the constant airline schedule changes (there will be more for sure, highly depending on the upcoming hurricane season), SXM remains a good hub to SBH. Being closer to SBH, SXM offers more airline / charter options compared to SJU, cheaper fares, and even has ferry options for late winter arrivals (a regular occurence when winter storms hit the North-Eastern US and Canada).
If I may add some information for new travelers coming to SBH:
Scheduled flights (= ticket sold by the seat) to SBH originate from the following airports only:
St. Maarten (SXM), San Juan (SJU), St. Thomas (STT), Antigua (ANU), St. Martin (SFG), Nevis (NEV). Airlines include: St Barth Commuter, Winair, Tradewind Aviation.
This is the cheapest option to get to SBH by air and obviously would need to match the existing commercial flights (to SXM as listed by Thomas, to SJU, STT or ANU). St Martin and Nevis are not used as international hubs (although several commercial flights from St. Martin to/from Guadeloupe are offered daily).
Charter flights (= private/whole aircraft) to SBH originate from most airports in the Caribbean & Florida. As a charter broker,
Caribbean Flights offers the following aircraft:
From SXM (St. Maarten): De Havilland Twin Otter (16 seats), Cessna Caravan (7/8 seats), Britten Norman Islanders (7/8 seats), Helicopter (5 seats)
From ANU (Antigua): De Havilland Twin Otter (16 seats), Pilatus PC 12 (6/8 seats), Cessna Caravan (7/8 seats), Britten Norman Islander (7/8 seats), Piper Aztec (5 seats), Helicopter (5 seats)

From MIA (Miami) (

(Direct flights to St. Barth from Mustique, Tortola, Virgin Gorda, Dominica, Barbados, St. Lucia, Punta Cana, La Romana, Providenciales, Cuba.... are also available on our own Pilatus 6 seats, Piper Aztec, or Cessna Caravan...).

Chartering an airplane is often more expensive than flying on a scheduled flight (there are exceptions), but it offers VIP service (both at the airport and on board), schedule flexibility (particularly important in case of delays), expedited airport transit (skipping TSA/immigration lines, baggage transfer...), and always comfort, convenience and safety.
