I wonder, what happens if I would want to use a contract lounge in an airport (let's say OTP) that allows access to the only *A airlines that fly there (LH, LX, OS) but have *G status on a different *A airline (like TG)? Would they let me in? Is there a specific rule for such cases or would I be left in (shudder) the hands of the gate agent's willingness? I would be traveling in Y, hence no other possibility of access...
