Air Tahiti Nui uses the LAX International Lounge – or more formally, Los Angeles International Lounge at LAX. I hadn’t visited this lounge before, and my expectation were low – but exceeded.
The Los Angeles International lounge is used by El Al, Air Tahiti Nui, Philippine Airlines, Fiji Airways. The lounge is also used by Japan Airlines for premium economy passengers. It was basically empty while I was there, and seems a perfect candidate for Priority Pass, but it isn’t accessible through any lounge access programs – just with a qualifying boarding pass.
