Panama City–Bay County International Airport (IATA: ~~ECP~~, ICAO: ~~KPFN~~, FAA LID: ~~PFN~~) was a public airport three miles northwest of Panama City, in Bay County, Florida. It was owned and operated by the Panama City–Bay County Airport and Industrial District. All airline services moved to the Northwest Florida Beaches International Airport on May 22, 2010, but the airfield was open to general aviation aircraft until October 1, 2010. The grounds will eventually be turned over to LUK-MB1 LLC, which plans to remove the runways and build homes, shops, walking trails and a marina.

Panama City–Bay County International Airport (PFN) began as a private field owned by J.B. Atkinson, Jr., a citizen of Panama City. The facility had 292 acres (1.2 km²) of land with grass landing strips. In 1932 Mr. and Mrs. Atkinson, Jr. donated the property to the Panama City Chamber of Commerce so a city airport could be established. At that time the airport was named Atkinson Field. In 1938 Panama City and the Bay County Commissioners joined forces to develop the Airport through the construction of an airport terminal and extensive airfield expansion. The facility’s $604,000 development project included the construction of a small passenger terminal and two 4,000-foot (1,200 m) intersecting runways. After the expansion was completed, the airport was renamed Fannin Field in honor of the Panama City mayor during this period.

Through World War II the airport was a Civil Air Patrol facility, the location of Coastal Patrol Base 14. In 1943 the Florida legislature approved the formation of an airport authority, the Panama City–Bay County Airport and Industrial District, to manage Fannin Field, or Panama City–Bay County Airport, as it became known. In 1948 commercial scheduled passenger airline operations began.
