How Did San Diego International Airport Become the Busiest Single-Runway Airport?
The evolution of this airport is a story of vision, innovation, and determination. It all began at Dutch Flats, a tidal marsh that was gradually reclaimed by the city of San Diego. Early in its history, influential figures recognized the strategic value of this land. In 1913, Congressman William Kettner persuaded military leaders to set aside this area for aviation, and by 1921 the Marine Corps Recruit Depot was established nearby.
In 1920, Ryan Airlines—then a fledgling venture—set up one of the first civilian flight schools on this land, paving the way for commercial aviation. The facility built and test-flew the aircraft later used in Charles Lindbergh's historic transatlantic flight. In 1928, the airport was first opened as San Diego Municipal Airport - Lindbergh Field, named after Charles Lindbergh to honor his pioneering spirit. This airport quickly grew into the first commercial airport in the region, setting a foundation for decades of growth.
Over time, the airport developed into the busiest single runway airport in the U.S. thanks to a combination of geographic inevitability and careful planning. The city of San Diego recognized early on that expanding the facility beyond its current footprint was hard due to surrounding urban development and military installations. Thus, it continued to innovate within the existing limits.
