Charles M. Schulz-Sonoma County Airport

The airport initially opened in 1942 as Santa Rosa Army Air Field, and it was assigned to the Fourth Air Force as a group and replacement training airfield, with pilots sent to combat units overseas. Fighter Groups at the airport included the 354th, 357th, 363d, 367th, and the 478th. On January 31st, 1946, the airfield was inactivated (as WWII had concluded) and was turned over to the War Assets Administration to convert it into a civil airport. From the late 1940s to the mid-1970s, the airport was serviced by Southwest Airlines, followed by its successors Pacific Air Lines and Hughes Airwest, who flew mainly to San Francisco. Over the years, various commuter airlines also serviced the airport, including Eureka Aero, Westates Airlines, Wings West Airlines (operating for American Airlines), WestAir (operating on behalf of United Airlines), and others. During the early to mid-00s, the airport had no scheduled flights. In March 2007, Horizon Air began flights to Seattle/Tacoma and Los Angeles, meaning that scheduled air service had resumed (the airline was retired in 2011 by Alaska Airlines, so all those flights are now under the Alaska Airlines name). In recent years, Allegiant Air started service in May 2016, ending in June 2017.
Furthermore, Sun Country Airlines began seasonal flights in March 2017, which, indeed, was in 2020. However, American Airlines (under codeshare with SkyWest Airlines as America Eagle) added routes, United Express made its return, and Avelo Airlines began flights in April 2021. As for the airport itself, a project was started in August 2013 to decouple the ends of two runways, which would allow for the extension of runway 14/32 by 885 feet (to 6,000 feet), and for the extension of runway 02/20 by 200 feet (to 5,202 feet). An influx of passengers in the late 2010s forced the airport to expand. As a temporary solution, a “tent” was built to serve as gate 2, allowing the airport to double the area for outbound passenger seating while opening a second passenger screening lane with TSA Pre-Check capabilities and replacing portable restrooms with permanent ones (at the cost of $4 million). The “tent” was opened on October 22nd, 2021, while a more permanent solution was hatched, the construction of a new terminal building that would cover 40,000 square feet, with a new gate 1, additional space for concessions, an outdoor patio with seating and dining, two new baggage claims systems, relocation of rental car desks, a new ticketing lobby, and the relocation of two passenger screening lines from the gate 2 tent (at the cost of $31 million). The new terminal was scheduled to open in October 2022, although, according to their website, that has yet to happen.

The airport is seven miles northwest of downtown Santa Rosa.
