Are you sure about this? Does a codeshare always mean that the rules of the airline have the codeshare flight # and not the operating airline apply for mileage purposes? Is this only for AA or is industry wide? Sorry to ask keep getting conflicting replies and so link to a reliable source would be appreciated.
