Terminal 3 Formerly known as the "North Terminal", Terminal 3 is composed of Boarding Area E with 13 gates (gates E1-E13) and Boarding Area F with 23 gates (gates F1-F3, F3A, F4-F22). Terminal 3 is used for United Airlines' domestic flights. Mainline United and United Express flights use both boarding areas. This $82.44 million terminal was originally designed by San Francisco Airport Architects (a joint venture of John Carl Warnecke and Associates, Dreyfuss + Blackford Architecture, and minority architects). The groundbreaking ceremony for the North Terminal was held on April 22, 1971, and Boarding Area F opened in 1979 and Boarding Area E opened in 1981.
