Yes and no. I agree that Colombia has its own unique practice of both boarding and exiting. That's really the fault of the airlines. They don't attempt to do anything to change the behavior.

The one and only time that I have arrived in BOG at a pod when traveling Copa, they had a separate van (Not a bus) which was waiting for those of us in Clase Ejecutiva. One of the FAs stood between the cabins to hold back the masses, and there was an announcement that they would be first allowing CE pax off the plane, then a bus would arrive for those in economica.

I have never departed BOG from a pod when flying Copa, so I don't know if they have the same practice, but it made a huge difference in the total premium cabin experience.

Boarding the bus first as a premium cabin passenger is actually a disadvantage. We get buried behind those that are crammed onto the bus after us, so we can't get off the bus first. All we get to do is spend more time on that uncomfortable, overcrowded bus.
