There is no urban transport line between the international airport Armando Tola and the city, the distance is 22 km and the only way to get to the city is to take a remisse or cab at the airport or hire a transfer service as soon as you get off, although you can book in advance to make sure they are waiting for you.
If you decide to rent a car, all the “Rent a Car” agencies have a stand at the airport, in fact it is very useful to leave in the vehicle from the airport. It is very easy to get from there to your accommodation in the city. Especially in high season it is advisable to make a reservation.
