Im sure OW will not be able to fix my specific problem, but I am not the only one having these types of problems, as I have seen from posts in Advantage and where Lan is posted. Im sure OW oversees the proper functioning of their partners mileage handling and there is something of a glitch in the way Lan, or Lan Argentina is functioning which should be addressed to OW, at least this is the way I see it. They are bound by what they advertise and if LAN doesnt honor miles on a fare they advertise as eligible for miles, something is really wrong in here
