I am looking to book a CX Economy ticket. I have no status with CX but have silver status with BA.
Must I put my BA Frequent flyer programme info when booking at CX site to entitle business lounge access?

Can I show my BA silver status membership card and CX boarding pass (which does not show my BA status) at the business lounge to gain access? The reason is I want to earn CX Asiamiles for this trip.

Thanks for your advice.
