Well for AS members, this should cover all of AS partners, though AA only works for International. though bad part is fare class exclusions are not possible. Though some additional -'s may be necessary based on destination like I just had one with Virgin Atlantic/SQ combo which is not wanted. I actually saw Options i would not have considered like HU/SQ combo.
