ExpertFlyer shows numbers (all zeros for the flights/dates I'm interested in) for "C" inventory on AA codeshares operated by BA (i.e., AA flight numbers in the 6000 series). Can SWUs be used on these flights? Am I mistaken to think that SWUs can only be used on AA metal?
SWUs cannot be used on codeshares. In fact, be careful about buying AA ticketed/US operated and vice-versa. Generally you need operated and ticketed to be the same carrier to use a SWU.
