SDQ to other Caribbean locations

Unfortunately, flying within the Caribbean is relatively expensive. The DR does not have many direct flights to the smaller islands, these are usually reached via Miami or San Juan (Puerto Rico).

I've flown to Cuba, Puerto Rico and Haiti direct, and to Jamaica, Barbados, St Vincent and St Lucia via San Juan. Last year I also took the much less expensive option of a ferry to Puerto Rico - highly recommended.
