It'll mostly be HKG-JFK in biz with occasional leisure travel ex-HKG or ex-JFK/LGA in coach.
The problem with lounge access is, when I travel in leisure (either ex-HKG or ex-JFK/LGA) it would be with family of 4 (2 small kids) and not every lounge makes an exception of allowing me to bring extra guests based on status (e.g. HKG Qantas lounge was a yes, NRT Sakura lounge was a no). Priority pass works well enough in HKG and some other places we usually travel to (TPE/LHR/etc) but not so much in NRT/JFK, which is why partner status is appealing, but as CPH-Flyer said, it's probably at least a year away. When I travel for work it's not an issue at all, with the slight benefit of having OW Emerald gets me to F lounges in Wing/Pier or JAL first class lounge, which is why the ease of obtaining emerald is also a consideration.
