Dear BA fellows,

I just had my first BA experience booked . Although the city where I live is only blocks away from the one where no-spa-damn-BA-er lives, I am aware of the rule that I am not entitled to enjoy the spa. I am sure BA's excellent service is still ^ ^ without spa.

Here are my questions (As a AA platinum, OW Sapphire)
At HKG, I can use BA FIRST lounge or CX business class lounge. Will CX let me use their FIRST lounge?
At LHR, I can use BA Terrace departure lounge. Will BA let me access their FIRST departure lounge? I don't wanna hike to T1 arrival lounge just for a breakfast and getting a s~~~~~~pa~~~~~~ treatment.
