Several major air carriers schedule regular service to both Key West and Marathon airports.  Many flights are routed through the Miami International Airport, although some smaller airlines schedule direct flights from many major cities in Florida and the Bahamas. International flights must connect to one of these airlines in Miami. Check with the airline carrier for specific flight information. The Marathon Airport is located roughly 120 miles south of Miami. The Key West Airport is located about 180 miles southwest of Miami International Airport. Both airports offer car rental services.
