A particular kind of traveler now has a compelling new option in the middle Florida Keys: the ability to step off a private jet and be home in 15 minutes. This seamless transition from tarmac to front door is reshaping the luxury real estate market near Marathon International Airport, which has undergone significant upgrades in recent months.
Marathon International Airport completed a $30.1 million runway relocation in October 2025, bringing the facility into full FAA compliance and enabling it to accommodate a wider range of aircraft. The upgrade was followed by Million Air completing a $5 million fuel farm project, bringing two 30,000-gallon jet fuel tanks online. Monroe County commissioners recently backed an $11 million initiative to restore commercial air service to the airport for the first time since 2009, with carriers such as Delta Airlines and American Airlines under consideration for routes to Atlanta and Miami, respectively.
Million Air, the premium fixed-base operator with locations across exclusive destinations, is known for delivering a red-carpet private aviation experience: dedicated jet terminals, private lounges, ground transportation coordination, catering, and concierge services. For buyers accustomed to that level of service at airports in Aspen, Palm Beach, or the Hamptons, finding it at the doorstep of their Keys estate changes the calculus of ownership entirely.
The residential enclave of Stirrup Key, just minutes from the terminal, has become shorthand for a new kind of Keys lifestyle. "You can step off your plane and be in your home in fifteen minutes," says Margie Casey, a Certified Luxury Home Marketing Specialist with Duck Key Realty. "Where else in the country can you do that? Not Miami – Miami takes three hours in traffic. Here, it’s fifteen minutes, door to door."
The investment pouring into the airport reflects a reading of demand that aligns with what real estate professionals have observed over the past 12 to 18 months. In a recent six-month window, the middle Keys recorded five property transactions between $12 million and well over $20 million, compared to a single sale above $9 million in the equivalent period a year prior. These are considered long-term commitments to a place that buyers are treating as a primary base.
The Florida Keys offer what no other American destination can match: the Caribbean without a passport, with domestic infrastructure, US property law, and the ability to drive home when international travel becomes complicated. The waters surrounding the Middle Keys represent one of the most diverse sportfishing environments on the planet, with the Marathon Humps drawing offshore anglers for sailfish, marlin, wahoo, and mahi-mahi, while nearshore flats offer backcountry light-tackle fishing for bonefish, permit, and tarpon.
