Hi All. I am an AA Exec. Plat. (OW Emerald) traveling JFK-LHR-ATH-CHA this Sunday. The JFK-LHR and LHR-ATH flights are on AA and BA respectively. My onward brief flight from Athens to Chania (Crete) is with Olympic Airways.

Unfortunately, I have a 4 plus hour layover in Athens. I believe that technically I'm not allowed access to any OW lounges due to the fact that my onward flight is not on a OW carrier. Is that right? If so, what are the chances they might make an exception (considering the previous 2 legs and Emerald status) and allow me in? Any and all help appreciated.
