Frontier Airlines will begin service this year to and from Southern California's Ontario International Airport.
Officials announced Tuesday that the Colorado-based low-cost carrier will offer flights to Austin, Texas, and Denver starting in October.
Service to Chicago's O'Hare will begin in 2018.
Frontier says the new routes are part of a nationwide expansion.
Ontario International is in the inland region about 40 miles (64 kilometres) east of Los Angeles. It recently was restored to local control after 20 years of ownership by the city of Los Angeles.
