The 1990'S
In the 1990s, the consolidated rental car terminal and Terminal A opened (1998). Meanwhile, passenger traffic continued to grow. Sacramento Metropolitan received a new name – Sacramento International Airport. The consolidated rental car terminal, the first of its kind in the nation, placed all rental car companies in one building that was serviced by airport-run shuttles. This innovation streamlined bus operations to reduce congestion at the terminal curbs and improve air quality while also enhancing overall customer service.
Over the years, advances in technology changed how the airport shared information with its customers. The Sacramento County Department of Airports launched its first web site in April 1997.
During this time, airline service also changed. Southwest (1991), Alaska (1993), Horizon (1993), and TWA (1994) were added to the list of carriers serving Sacramento. Southwest and Alaska Airlines experienced rapid growth, offsetting the departure or cessation of operations of airlines other airlines.
The New Millennium
The new millennium ushered in even more changes, none more significant than those following September 11, 2001. Airport security procedures were forever changed by the tragic events of that day. The newly-formed Department of Homeland Security and Transportation Security Administration were created and sweeping changes were implemented to improve aviation security.
Despite the immediate effects on air travel, September 11 did not deter growth at Sacramento International Airport. Four new airlines were soon added to Sacramento International: Continental returned (2000) and Frontier (2002), Mexicana (2002), Hawaiian (2002), and Aloha Airlines (2003) initiated service. Mexicana’s arrival initiated international nonstop service and necessitated completion of the International Arrivals Building for the federal inspection services prior to the first international arrival at Sacramento International Airport. Sacramento County Department of Airports paid for customs service until 2006, when Sacramento was designated as an official "port of entry."
The new parking garage opened September 23, 2004 to rave reviews. The six-story structure offered covered parking, a short walk to the terminal and public art (“Flying Gardens” by Dennis Oppenheim and “Flying Carpet” by Seyed Alavi). As of October 6, 2011, the parking structure connects to both Terminals A & B.
In 2006, Sacramento International Airport became one of the first airports in the nation to offer free wireless Internet service (WiFi) to its customers.
