The airport's first Jet Age terminal (now Terminal 1) was designed by John Carl Warnecke & Associates and opened in 1962, part of a $20 million expansion on bay fill that included the 10,000-foot (3048 m) runway 11/29 (now 12/30). The May 1963 OAG showed 15 airline flights arriving in Oakland each day, including nine from San Francisco; in June 1963, TWA flew Oakland's first scheduled jet, a Convair 880, to Chicago. American Airlines scheduled service from Oakland to Phoenix then into Dallas using the Boeing 720 aircraft. Pacific Southwest Airlines (PSA) provided several flights within California from OAK using Boeing 727 and DC-9 aircraft. United Airlines introduced non-stop service to Chicago, and on the San Francisco-Oakland-Los Angeles route using the Boeing 727.
