Recently while travelling from San Francisco to New York on an around the world trip, we checked into the United Club Lounge at the San Francisco Airport.
There are two United lounges in Terminal 3, and we visited the bigger of the two and closer to gates 70-80. This lounge although bigger has not been renovated to the new style of United lounges, despite this it was still very comfortable and because of the size of the lounge, it felt very exclusive.
