Florida Keys Marathon Airport, public airport located in Marathon, in Monroe County, Florida
Florida Keys Marathon Airport is a small public airport in Marathon, Florida, situated along the Overseas Highway. The facility spans about 197 acres and has one asphalt runway that primarily handles private and small general aviation aircraft.
The airport was built quickly during 1942 and 1943 during World War II and served the Navy as a training and security base. After the war, the facility was transferred to Monroe County and evolved into a civilian airport for private flights and regional aviation.
The airport takes its name from the nearby town of Marathon, reflecting the local identity of this Keys community. It serves as a gathering place for pilots and travelers who value the relaxed pace and feel connected to the region's history and character.
The airport offers free parking and rental car agencies including Avis, Budget, and Enterprise at the terminals. Taxi services like Key Hopper Taxi and shuttle services such as Keys Shuttle are also available to transport visitors to local attractions and beyond.
The airport once had scheduled airline service that lasted more than 25 years, but this was discontinued and today it focuses mainly on private flights and charter services. A notable addition was the reopening of the U.S. Customs facility in 2016, allowing international travelers arriving by private plane to clear customs directly at the airport.
