Singapore Airlines will close its San Francisco SilverKris airport lounge on October 1, 2017 in order to create a massive split-level Polaris business class lounge for Star Alliance partner United Airlines.
United's new Polaris lounge – which will be built in the footprint of the current United Club, just past the airport's security screening zone – will also swallow up the adjacent EVA Air lounge, and is scheduled to open in early 2018.
It will be be one of the largest Polaris lounges in United's network, offering plenty of room for the promised dining areas (above), bar, work booths, daybeds (below) and shower suites.
However, access to that lounge will be restricted to business class and first class travellers on United and Star Alliance partners such as as Singapore Airlines.
In the meantime, the United Global First Lounge – located further along the terminal, between gates 98 and 100 – will become a temporary United Club.
Frequent flyers travelling in economy or premium economy will make their way to the airport's less-salubrious United Club lounges, one of which will spring up – using the newest United Club concept – in the downstairs space of the current Global First lounge near gate 94.
Singapore Airlines' San Francisco lounge is widely considered to be among the worst in the SilverKris network with cramped and tired seating and a sub-par buffet, so the new Polaris lounge will be a definite upgrade – as long as you're flying at the pointy end of the plane.
