Do you fly US Domestic? BA Silver will give you lounge access when not flying on CX.
Your profile says you already have BA Silver - what do you like about BA silver vs CX?
I rarely fly US domestic. But I thought CX Gold will allow me to get into the AA domestic lounge as well?
BA Silver is has a good earn/burn ratio and the household account comes in handy! Also, there is a 50% avios bonus which is great! Especially, I can even earn TPs when I am flying on cheap intra-EU fares. But the one consideration is, it seems CX gives better soft-perks to its own MPC members...
