I think the reLAX lounge is closed. It's not listed on Priority Pass anymore, and Yelp says it's closed.
The Priority Pass lounge is now the KAL lounge (assume this is the Skyteam lounge).
According to the TBIT map, these are the lounges now:
• 5th Floor:
oneworld Alliance Lounge
KAL Lounge
Qantas Lounge
• 6th Floor:
Star Alliance Lounge
Etihad Airways Lounge
LA International Lounge
Emirates Lounge
Sorry, I was thinking of the 6th floor LA international lounge, which is probably the worst lounge there and is indeed not the priority pass lounge. If also forgotten about the Etihad lounge...
