More about Marathon Airport

Marathon Airport (KMTH, MTH) is a focused private-jet arrival point in Marathon, Florida, for travelers shaping a Keys itinerary around Key West. The field places the trip in the island chain from the first step off the aircraft, with the Gulf, the Atlantic, and the slower cadence of Marathon close at hand.

Private flying here is about simplicity: one coordinated arrival, an aircraft-side plan, and ground transportation arranged before the wheels are down. Instead of building the day around a commercial gateway, a charter through KMTH can keep the airport portion compact and intentional, particularly for travelers whose plans belong in Marathon before continuing through the Keys.

From a planning standpoint, KMTH is defined by its Marathon location, its Key West service, and a longest runway of 5,008 feet. The charter route set links Key West with Aspen, Cabo San Lucas, Cancun, Charleston, Chicago, Dallas, Geneva, Hilton Head, Honolulu, Houston, Ibiza, Jackson Hole, Las Vegas, Lisbon, London, Los Angeles, Miami, Monterey, Nassau, New York, Orlando, Paris, Providenciales, Puerto Vallarta, Rome, San Diego, San Francisco, Santa Barbara, Scottsdale, and Seattle, giving advisors a broad map for one-way or round-trip proposals.

Key West International Airport (KEYW), Miami-Opa Locka Executive Airport (KOPF), Miami Executive Airport (KTMB), and Naples Municipal Airport (KAPF) can all enter the conversation for the same destination set. A private traveler may still choose KMTH when the trip is centered on Marathon itself: the airport’s setting keeps the arrival in the Keys, while preserving a clear Key West charter plan.

Marathon has a quieter, water-level feel than a city arrival, with marina life and open-sky crossings setting the tone. For Amalfi Jets clients, that sense of place is the point: the journey stays polished, but the arrival feels unmistakably Florida Keys.

Advisor Note

“We firm dates and route priorities first, then confirm handling and aircraft options around the 5,008-foot runway; early commitment helps widen the search before the best-suited aircraft are held elsewhere.”

Common questions about Marathon Airport charter

Can I fly private to Key West through KMTH?

Yes. Marathon Airport serves Key West, and the listed charter routes include Key West connections with Miami, New York, Chicago, Dallas, Los Angeles, London, Paris, Cancun, Nassau, Cabo San Lucas, Aspen, and other cities in the published route set.

What runway length should my advisor account for at KMTH?

Marathon Airport has a longest runway of 5,008 feet; your charter advisor should match the aircraft and operating plan to the trip rather than assume suitability from runway length alone.

Why might I use KMTH instead of Key West International, Opa-locka, Miami Executive, or Naples?

Choose Marathon Airport when your plans are centered on Marathon, Florida, while still using a Key West charter itinerary; Key West International Airport (KEYW), Miami-Opa Locka Executive Airport (KOPF), Miami Executive Airport (KTMB), and Naples Municipal Airport (KAPF) can also be reviewed for the same destination.

Which airport codes should I give for a charter request?

For flight planning and charter requests, Marathon Airport is identified as KMTH by ICAO and MTH by IATA.

Can KMTH be used for longer Key West charter pairings?

Marathon Airport appears in the provided route set for Key West pairings with international points such as London, Paris, Geneva, Lisbon, Rome, Ibiza, Cancun, Cabo San Lucas, Nassau, Providenciales, and Puerto Vallarta, as well as U.S. routes including Miami, Orlando, New York, Chicago, Dallas, Houston, Los Angeles, Seattle, and Honolulu.
