I am OW Sapphire. I will be traveling on an AA award ticket in coach from LHR-BOM, with a long layover in BAH.

Does anyone know if I will have access to a lounge or premium check-in in BAH?

Since Gulf isn't a full member of Oneworld, I'm not sure what the policy is. Also, I believe that Cathay has a lounge at BAH. If I can't get into the Gulf lounge, is Cathay's lounge an option even though I'm flying Gulf?
