I flew LAX-BNE as a Plat in J, 1 week ago.
Made it through security by 6pm, to be told the EY lounge opened at 6.30pm!
Figured to try my luck at the Star Alliance business lounge round the corner. They scanned the boarding pass, light turned green, and they let me in. Ate some food there, then went across to the EY lounge when it opened. They didn't scan the boarding pass, but had a checklist of eligible passengers.
The EY lounge seemed quieter. I believe only the VA flights are using this lounge at the time. Interestingly, the a-la-carte dining is not offered for the VA flights, only for the EY flights which are earlier in the day!
I didn't try to access the Star Alliance first class lounge.
