I have to disagree with Flyrights and Flyme2. Frequent flier miles do not cost the airlines very much money. Award seats tend to be seats that would have gone empty anyway. You cant translate the value of 1,000,000 miles at 2cents a mile. Please remember there is more than one airline invovled here--Each airline shoulders a portion of the cost. Even it everyone were to claim awards with the partnership airlines or Hilton, airlines have back office systems to recliam miles and they sure don't do it 2 cents a mile.
LatinPass will be around for a long time--many of the airlines in the program are the flagship airline of their host countries and with that comes government subsidies.
