The Dominican Republic runs almost entirely on three airports — Punta Cana, Puerto Plata and Santo Domingo — and on one season: December to April, when direct flights from Canada multiply. Outside that window the supply thins and connections return. Punta Cana and Santo Domingo are four hours apart by road: the choice of airport is not a detail.
The arrival airports
One airport, one page. Two airports of the same city stay apart: a deal to one is not a deal to the other.
