See privacy policy.United’s Polaris Lounges are intended to be exclusive, and they are — access is limited to passengers flying in United Polaris, or those traveling in business or first class on a long-haul flight operated by another Star Alliance carrier. From time to time, there are other opportunities to gain access, though.Currently, United is offering up tickets to attend a Polaris Cookbook event at the airline’s SFO location. For 5,000 United miles (worth $70 based on our valuations), you can confirm access on Monday, Dec. 10, from 7pm until 10pm.You’ll have a rare opportunity to experience United’s SFO Polaris Lounge.

I’d expect them to go quickly, though, so be sure to redeem quickly if you’re hoping to attend.
