You must find the TU LLAVE stand at the airport in order to buy a Transmilenio-card which wills allow you to move around the city. You must take into account the journeys you will make. Take the M86 Bus to El Dorado Station where you can take the route to your desired destination.
Transmilenio operates generally between 4 in the morning and 11 at night, from Monday to Saturday. On Sundays, the schedule is reduced from 5 in the morning to 9:30 at night. The exact information depends on the date, the station and the line.
