Live delay counts and on-time performance are calculated on the full dashboard using schedule comparison data.
The Blue Board is the only real-time operations dashboard built specifically for United Airlines passengers. Live flight tracking, delay alerts, Starlink WiFi status, and IRROPS monitoring, updated in real-time.
This page gives you the overview — but the real action is on the dashboard. Track every United flight at SFO in real time, set up flight watch alerts, check equipment swaps, and monitor weather radar overlaid on the live map.
San Francisco International Airport is United Airlines' primary Asia-Pacific gateway and a critical hub for the tech corridor connecting Silicon Valley to the world. With approximately 300 daily departures, SFO connects to over 130 destinations domestically and internationally.
United domestic flights operate from Terminal 3, while international flights use the International Terminal (Terminal G). United Club lounges are located in Terminal 3 (Boarding Area E near gate E4, Boarding Area F near gate F11) and the International Terminal Boarding Area G, including a United Polaris lounge for premium international travelers. United Express regional partners operate from Terminal 3.
San Francisco International has a unique delay profile driven primarily by fog and runway configuration. Understanding these patterns is essential for SFO travelers:
Paradoxically, summer is SFO's worst season for delays. Marine layer fog rolls in from the Pacific, reducing visibility and forcing SFO to switch from dual parallel approaches to single-runway operations. This cuts arrival capacity roughly in half and triggers ground delay programs that ripple across the network. Fog is typically worst in the morning and evening.
Pacific storm systems bring rain and low ceilings. While less impactful than fog, sustained rain events reduce approach rates and can cause moderate delays. Atmospheric rivers can produce extended periods of reduced operations.
SFO's closely-spaced parallel runways (28L/28R) are only 750 feet apart — too close for simultaneous independent approaches in instrument conditions. This is the structural reason fog has such an outsized impact on SFO operations compared to other airports.
United Airlines is actively equipping its fleet with Starlink satellite internet — the fastest WiFi ever offered on a commercial airline. SFO-based narrowbody and widebody aircraft, including 737 MAX 8, 737 MAX 9, and A321neo, are among the first aircraft types receiving Starlink installations.
Use The Blue Board's Fleet tab to check if your specific aircraft has Starlink. You can search by tail number, flight number, or aircraft type.
Check the live status panel at the top of this page for current on-time performance, delay counts, and cancellations. For flight-level detail, open SFO on The Blue Board to see every flight in real time.
United domestic flights operate from Terminal 3. International flights use the International Terminal (Terminal G). United Club lounges are in both terminals, and a Polaris lounge serves premium international travelers.
Approximately 300 daily departures, making SFO United's primary Asia-Pacific gateway and a key West Coast hub.
Starlink is being installed on narrowbody aircraft first (737 MAX, A321neo). Check the Fleet tab for the latest count and specific tail numbers.
