Airport History



Mammoth Yosemite Airport (MMH) was originally constructed by the Unites States (U.S.) Army for use as an auxiliary landing strip during World War II. After the war ended, Mono County acquired part of the airfield from the U.S. Army and renamed it Long Valley Field.

In 1965 the runway was extended from less than 4,000 in length by 30 feet to 5,000 feet in length by 100 feet, and again in 1971 was extended to 6,500 feet in length. By this time the airport had been renamed Mammoth Lakes Airport, but underwent another name change to Mammoth-June Lakes Airport in 1972. Starting in 1973 through 1980, Sierra Pacific Airlines flew into the airport using Convair 440 aircraft.

During the early 80's, the runway was increase to 7,000 feet in length by 100 feet, which is still the current dimensions today.


In 1993, the Town of Mammoth Lakes acquired the airport from Mono County. During the early to mid-90's, United Express and Trans World Airlines briefly provided commercial service to MMH. In 2000, the Town of Mammoth Lakes changed the name of the airport to Mammoth Yosemite Airport.

In 2008, Alaska Airlines began daily service to MMH from LAX using the 76 seat Bombardier Q400. In 2010, United Airlines began service from SFO using the 70 seat Bombardier CRJ 700. By 2013-14, destinations included LAX, SNA, SAN, and SFO. Flights to LAS and DEN were also included for the 2014-15 season. Airline service continued to a number of these locations through March of 2020, at which time commercial service was discontinued.


The Town of Mammoth Lakes remains the owner and operator of Mammoth Yosemite Airport. In November 2021, Advanced Airlines began Scheduled Part 135 Charter Service into destinations included Hawthorne (HHR) - Los Angeles, Carlsbad (CLD), and Burbank (BUR) seasonally.
