The Marathon Airport opened its doors in 1943.
The Airport is commemorating 75th years of aviation in the heart of the Florida Keys with a free celebration on Oct. 20, 2018, from 9 a.m. to 5 p.m.
The Marathon Airport opened in 1943. It was built by the U.S. Navy as an auxiliary airfield for Naval Air Station Key West. It was deactivated as a military facility at the end of World War II and transferred to the Monroe County Board of County Commissioners for use as a civilian airport.
For most of its existence, the County owned-and-operated airport has been a general aviation facility. It also has had scheduled passenger airline service for more than 25 years in the past.
On April 20, 2016, for the first time in approximately three decades, U.S. Customs and Immigration service became available at the airport with the completion of a new 4,200-sq-ft permanent Customs and Border Patrol facility located in the former commercial terminal.
Marathon Airport also served an important role during the Screwworm outbreak in 2016 and the response to Hurricane Irma in 2017.
