Hi, it's been 40 years since I last connected through JFK, I'm hoping for a smooth experience this time and would appreciate any "top tips" to make the connection better!

I'm BA Gold, UK passport and have ESTA, Global Entry and TSA pre
In March next year, Flying EZE - JFK on AA 954 (arrives 7:00am) Connecting to AA 6939 (BA178) JFK - LHR (departs 9:05am). All on 1 PNR and all ticketed with AA

I'm guessing that it will all be through T8 and that I'll need to re-check my bags.

Questions.... Is that a busy time of year/day... will I be in a hurry or relaxed? (assuming AA 954 is on time!) Is it a long haul to the lounges? Are there any "short cuts" or interesting routes in the terminal? Any other tips that would make connecting more fun?!
