Stephenville Airport (IATA: YJT, ICAO: CYJT) is an airport located 1 nautical mile (1.9 km; 1.2 mi) south southeast of Stephenville, Newfoundland and Labrador, Canada. It was built by the United States Air Force and operated as Ernest Harmon Air Force Base from 1941-1966.
Stephenville Airport provides scheduled and charter air service to a catchment population of approximately 100,000 people, from the city of Corner Brook 65 km (40 mi) to the north to the town of Port aux Basques 120 km (75 mi) to the south.
In 1941 the United States obtained rights to construct a United States Army Air Forces base in the St. George's Bay area of Newfoundland. The U.S. 76th Congress approved the 99-year lease and in April 1941, construction began.
The USAAF base was built as Stephenville Air Base. However, after the USAAF became the United States Air Force in 1947, it was renamed Ernest Harmon Air Force Base on June 23, 1948, in honour of Captain Ernest Emery Harmon. Harmon was a US Army Air Corps ace who was killed in an air crash in 1933.
On September 1, 1943, the Newfoundland Base Command transferred control of Harmon Field to the North Atlantic Wing, Air Transport Command. The base became a part of the Northeast Air Command in October, 1950. Then in April 1957, the Strategic Air Command assumed control.
The mandate of the base was to maintain a tanker alert force and its capability to meet and refuel Strategic Air Command jet bombers en route to targets. The Boeing KC-97 Stratofreighter was employed in this task.
The base was also used as a refueling stop for transatlantic military flights. In addition, Harmon supported three Air Defense Command units. In 1957, the Canadian Department of Transportation constructed an airport terminal to accommodate Trans-Canada Air Lines (now Air Canada). 1966 saw the closure of the U.S. Air Force Base in Stephenville.
The airport is now owned and operated by the local airport authority, the Stephenville Airport Corporation Inc. Stephenville Airport was designated as an alternate in the Trans Oceanic Plane Stop (TOPS) program on 23 July 1970.
The Stephenville Airport was the major passenger airport for all of western Newfoundland until the early 1990s when provincial government decided to direct more traffic to the Deer Lake Regional Airport. All major carriers used Stephenville such as Air Canada, Eastern Provincial Airways and Canadian Airlines.
In 1970 the airport was designated by international scheduled air transport and for international general aviation regular use.
The Newfoundland and Labrador government's plan, called "Taking Flight", aims to enhance air travel in the province by working closely with airports and airlines. For the airlines, if they create a new route, the government can fund the new route up to $750,000 to help promote it.
Currently the airport is seeking opportunities with airlines to offer yearly service to southern Ontario and other mainland gateways. The service currently to St. John's is hoped to improve as demand in the region is there. 
Stephenville Airport has a current catchment of 100,000 passengers per year but service is limited and as a result those passengers have little choice but to use Deer Lake regional airport, located two hours north.
A yearly service with proper schedule and connection opportunities would easily have support from the region.
Operation Yellow Ribbon
On September 11, 2001, eight civilian airliners made unscheduled landings at the Stephenville Airport following the closure of North American airspace in the wake of the terrorist attacks on New York City and Washington, DC. As a participant in Operation Yellow Ribbon, the town managed to host nearly 3,000 stranded passengers for approximately one week.
