From Gary over at View from the Wing: As you know American and JAL are partners in the OneWorld Alliance. Between now and 1 November, 2011, American is offering a 50% discount on flights to Tokyo Haneda from San Francisco and to Tokyo Narita from Vancouver. This only applies to non-stop flights however. In addition there is a double miles promotion for some code share flights on JAL.
