UA operating from SFO Terminal 2
A few days ago the air-side connector between terminals 2 (gates D) and 3 (gates E, F and G) at SFO opened.
Starting yesterday it looks like UA is now using Terminal 2 for a small number of flights! Todays UA2617 (SFO-LAX) and UA1954 (SFO-DCA) have both departed from the D gates in Terminal 2, with the corresponding inbound flights (from LAX/LAS) also arriving into D.
