Quote from Latin Pass "Members enrolled in LatinPass or in any of the LatinPass Member Airlines participating programs from March 20th, 2000 or after will not be eligible for this promotion". I believe the key words are "member Airlines". The partners are not member airlines so KLM, TWA, etc, would be excluded. You have brought up an interesting question however because COPA who is a member airline uses Continentals One Pass program as its frequent flyer program. Would members of One Pass prior to March 20th be eligable.
