You can use the Transmilenio rapid bus service to reach the airport. The airport station is "Portal El Dorado". The rapid bus runs very frequently day and night, but it can be very crowded. Also, you are not allowed to take large luggage onto the bus, so if you have a suitcase you won’t be able to use the rapid bus. If this is the case, you can try catching the public blue SITP route P500 which also stops at the airport. Taxis are also another affordable and reliable method of reaching the airport.
