Has anyone had any luck with AA codeshares of BA in 2018?
I recently had a misconnection in LHR and was rebooked from an AA flight # on AA metal to an AA flight # on BA metal. I made it home, which was great, but now I'm trying to figure out how to approach the miles. The initial response on the phone was "no, we used to do it unofficially", but I have yet to exhaust all options (e.g. Twitter).
