I need of finding cheap flights in Colombia? Not all the time are the cheap airlines featured on Google Flights or other airline search websites. Here is a list of Colombian Airliners to help save you the trouble.
Where you are going within Colombia will determine on the airline you choose. So, keep in mind when comparing prices that not all airliners go to all the cities.
Avianca is by far the most popular airline in Colombia. They service all the major cities and generally have great prices. Also, they service international flights.. so.. chances are you are have flown with them.
VivaColombia Services all big cities as well as some smaller cities in Colombia. Be careful with this airline as they like to charge for extra bags. I would compare VivaColombia to Frontier in the USA.
Satena is a small airline that services smaller areas of Colombia. If you are looking to fly to the Pacific coast, you will need to fly with Satena or ADA. Satena planes are about the size of a private plane.
ADA is a regional airline that only services smaller towns and Medellin. Their planes are small 14 seater planes. If you are afraid of flying in normal sized planes, these might not be the way for you. However, it's a blast!
EasyFly is another budget airliner. The great thing about EasyFly is they service Medellin's local airport. This means when you fly to other cities, you won't have to go all the way to MDE (The main airport). Be aware, they also charge for carry on.
Chances are you have heard of Latam. They are a massive airline that services South America. You can find some killer deals through their website even a day or two in advance.
Side Note: Some airlines like Latam and Avianca offer two different rates. One for local residents and one for foreigners. I've never had an issue booking the "Local Rate". To get around any issues I always check-in online and have my digital boarding pass. I never need to go to the check-in counter. It also helps that I never check bags.
