Seems like best to have it
[QUOTE=DiverFiver;2863917]I was there this week. The immigration agent at arrival asked for it and most people in line were holding a printed copy. The line was just.
Out the door and took 50 minutes at 8:30 pm. Departing was 100% Biomig for Colombians and foreigners, so I never spoke with an agent.
The process was to scan boarding pass at the first electronic gate. The second gate was for passport. The entire process took 5 minutes. What an improvement.[/QUOTE]3 of my 4 trips to Colombia this year I was asked for it here on my outbound flight, Don't remember ever any one in Colombia asking for it. However I think they have a way of knowing if you did it on the computer when they scan your passport. Best to have it than not.
