Taxis: When heading to the city, it is best to use an airport-approved taxi. If you give the attendants at the taxi booth the address where you want to go, they write down on a piece of paper the taxi fare. If the driver asks for more money after arrival, just ignore him/her.
Shuttle buses (Bus Satelite) make their rounds starting at Eldorado Terminal and proceeding to the bus station, cargo terminal, Civil Aironautical building, then turning around to the Puente peatonal Cra.103; the Puente Areo and back.
The new TransMilenio line connects the Airport to the City's mass transportation system downtown (a 40-minute ride) and other city points. Mi Transmi y SITP finds the Transmilenio routes you need, while showing the remaining time prior to bus arrival at the station. Download at sitp.gov.co
