Lounge Access Question

Hello,

I will be traveling on my honeymoon on Oct 27 on AA/CX Redemption. I have significant free time between flights and I was wondering which lounges I would have access to.

Oct 27
AA MIA to JFK 6:40pm-9:46PM Booking Code Z (Admirals?)

Oct 28
CX JFK to HKG 1:30am-5:20am Booking Code U (BA Terraces? Admirals?)

Oct 29
CX HKG to BKK 9:10am-11:10am Booking Code U (The Wing?)

Thanks in advance for your help.
