In June 2018, I was traveling to CHQ ( exact route: IST-ATH-CHQ ) with a party of 3. At that time I didn't hold *G status so I was waiting at the public areas. However, one of the other members in the party had a TK*G status at that time and was admitted to the A3 lounge in ATH before our flight OA336. Also he was able to guest somebody as he guested the 2nd member of our party where I was the only one sitting in the public area. However, the ticket and each segment of it contained A3 operated and marketed flights as well so it's not the same situation with the OP where both of his legs are OA operated flights.
