Santo Domingo has two airports: the main one, Aeropuerto Internacional Las Américas, is 22km east of the city.
Most international flights use Las Américas. Direct connections include Antigua, Atlanta, Caracas, Havana, Miami, Newark, New York (JFK), Orlando, Pointpitre (Guadeloupe), Panama, San Juan (Puerto Rico) and St Maarten. The 3rd-floor food court and the one past arrivals are better bets than the limited, overpriced options beyond security by the gates. There are several ATMs in the arrivals area. Watch your bags. Cigar shops, cafes, pharmacy and gift shops are in the departures terminal.
A taxi into the city costs US$40, with little room for negotiation. An Uber to the Zona Colonial costs around US$30. The trip is a half-hour (26km). If other travelers arrive when you do, try sharing a ride. If flexible, carrying a light pack and prioritizing cost over comfort, you can walk around 100m to the right of baggage claim and grab a motoconcho (motorcycle taxi; RD$100) to take you to a gua-gua (minivan) stop on the highway.
Some taxis may be willing to take you from the city to the airport for less. Or grab any eastbound gua-gua from the city and get off at the airport turnoff (it's a regular stop on these routes); a pack of motoconchos will be waiting to ferry you the remaining kilometer or two.
The smaller Aeropuerto Internacional La Isabela Dr Joaquin Balaguer, around 20km north of the Zona Colonial, handles mostly domestic carriers and air-taxi companies.
AeroDomca (www.aerodomca.com), Air Century (www.aircentury.com), Dominican Shuttles and Aerolineas MAS (www.aerolineasmas.com) connect Santo Domingo, primarily Aeropuerto La Isabela, to Punta Cana, Samaná, Santiago and La Romana. Air Century also flies to San Juan in Puerto Rico and Port-au-Prince in Haiti, and Aerolineas MAS and Dominican Shuttles fly to Port-au-Prince in Haiti and to Aruba.
The taxi fare from La Isabela is about US$15. There’s no permanent taxi stand there, but at least one or two taxis meet every flight.
