Found a site that talks about all of these fares use airpass link. http://www.airtimetable.com

I do not know how many of these passes actually offer miles, but I can tell you for certain that the one offered by Taca does not offer miles on Airpass flights. These are highly discounted tickets and I doubt any offer miles but I am not certain of this.I have used the Taca pass in conjunction with Latinpass flights to travel around Latin America however. Cheap but no miles or flight credit. Hope this helps.
