San Juan, in Puerto Rico, has long runways and plenty of connections from the US mainland, and from there St Barths is 339 km to the east. Because the runway at St Barths is only 646 m, the whole flight is made in a small turboprop of the Caravan, Twin Otter or PC-12 class with a crew approved for the airport; no jet lands there. The alternative is a jet from San Juan to St Maarten and the 32 km hop from there, which makes sense only if the party or the luggage will not fit a small turboprop.

Miami to St Barths ›No figure is printed. We found no published charter-broker price for San Juan to St Barths that we would reprint under the section's rule, and the flight is a turboprop flight, which the jet prices published elsewhere in this section do not describe. Every quote we send is in US dollars, for the whole aircraft, and the price includes our service fee.
