You should choose your airport depending on your final destination, be it a city or a resort area. There are many airports in the DR, and many a tourist has found himself with a flight that puts him into an airport that is four hours drive away from where he is headed. Your easiest connections should be Miami and San Juan (Puerto Rico), but these only give you a chance of flying American Airlines. AA/American Eagle can put you into the Santo Domingo, Puerto Plata, Santiago or La Romana airports. An alternative flight is Aeromar that flies into Santo Domingo and Punta Cana from Miami.
