The Florida Keys Marathon Airport (KMTH) is a general aviation field sitting alongside the Overseas Highway in the heart of the Florida Keys, roughly midway between Key Largo and Key West. With a single hard-surfaced runway and no scheduled airline service, it functions as the main gateway for private and charter traffic serving Marathon and the Middle Keys.

Overview

KMTH is a general aviation airport serving the city of Marathon, Florida, in the middle of the Florida Keys. It has no regularly scheduled commercial air services, and instead handles private, charter and general aviation traffic for visitors to the Keys. For a simulator pilot the appeal lies in its striking island setting, with water visible from almost every angle of the approach and a straightforward single-runway layout.

Airspace & Location

The airport lies along US Route 1 (the Overseas Highway) in Marathon, Florida, in the middle of the Florida Keys chain, roughly 50 miles northeast of Key West and 54 miles southwest of Key Largo. En-route traffic in the area works Miami Center. There is no operating control tower at the field itself, and traffic is coordinated by pilots on the common frequency.

Runways

KMTH has a single physical runway, 07/25, 4,995 feet long with a hard surface and runway lighting. There is no ILS approach.

Radio & Navigation

Weather is available on the ASOS at 135.525 MHz. En-route contact is with Miami Center on 133.5 MHz, with Miami Radio also available on 122.6 MHz. The airport's CTAF/UNICOM frequency is 122.8 MHz.

Joining & Circuit Procedures

KMTH is an uncontrolled airport, and pilots use the common CTAF/UNICOM frequency of 122.8 MHz to announce intentions and coordinate with other traffic in the pattern.

Visual Reference Points

The airport sits directly on US 1, the Overseas Highway, which threads the length of the Florida Keys and provides an obvious linear landmark for the approach. Boot Key Harbor lies just to the south of the field, and Crane Point Museum, set in one of the last untouched tropical hardwood hammocks in the Keys, is a few miles to the west. The Sombrero Beach Road junction with US 1, near Mile Marker 50, marks the main business district of Marathon close to the airport.

History

During the aftermath of Hurricane Irma's landfall on 10 September 2017, Marathon Airport became one of the earliest points in the Keys to receive emergency relief, with Air National Guard C-130 transport aircraft landing every two hours beginning on the morning of 11 September to bring in needed supplies.

The Airfield Today

There are no regularly scheduled commercial air services at the airport; it operates as a general aviation and charter field. Million Air Florida Keys operates as an FBO on the field, with stated hours of operation from 0700 to 1900 and after-hours call-outs available. Marathon General Aviation also operates as an FBO, positioned to the east of the field near the approach end of runway 25.
