Air service is anchored by Ontario International Airport, a primary air gateway for the Inland Empire, with cargo operations complementing passenger airlines serving domestic and international markets. General aviation and cargo fields include Ontario Air National Guard Station, San Bernardino International Airport—a converted military base supporting cargo and corporate aviation—and desert airports in Barstow–Daggett Airport and Apple Valley Airport. Aviation planning involves the Federal Aviation Administration and regional economic development organizations supporting cargo flows tied to logistics operators such as Federal Express and United Parcel Service.
