I found this link that says you can earn 3K Distancia miles for signing up to the program, but I can't find it anywhere on TACA's website. I assume that the link has old info.

Is anybody aware of this promotion? I'm considering putting my father on a TACA flight to LIM since it's by far the cheapest fare, and am trying to maximize the mileage he gets.
