Port Largo : The Florida Keys' forgotten airport Key Largo's Port Largo airport ( KYL ), which closed in 1985, has largely been forgotten by all but longtime local residents, pilots, and aviation buffs. The airport, dredged from the ocean floor, was little more than a breakwater with a runway on top and operated for little more than a decade. Despite its diminutive size, Port Largo enjoyed commercial commuter airline service and became the center of a nearly two decade legal battle. The story of this unusual airport began in the late 1960s with an undeveloped, submerged parcel of land owned by the State of Florida on the Atlantic side of Key Largo. The State sold the parcel to a developer who dredged the area and constructed a breakwater that was paved with a 2,300 foot landing strip. It was agreed that the developer would eventually donate the property to Monroe County for use as a public airport. Dredging began in 1968 and the airport was opened in 1972. Below: This late '50s aerial postcard view of Key Largo around mile marker 99.5 shows the initial phase of the Port Largo development at the top of the photo. The area shown under construction was for private residences. The area that became the airport, just beyond the shore at top left, was still underwater at this point.

Bahamas Caribbean Airlines operated nonstop flights between Port Largo and Miami International Airport using 9-passenger Britten-Norman Islander equipment. This excerpt from the December 1, 1981 Official Airline Guide shows two daily flights and a one-way fare of $45. Bahamas Caribbean later changed its name to Air South. The Port Largo runway stands out at the center of this infrared satellite photo from 1985 (also courtesy of the USGS).  In the early 1980s, the property was purchased by New Port Largo, Inc, who intended to close the airport and build homes on the site. Upon learning this, Monroe County commenced litigation to block the closure and gain legal control over the airport, and even changed zoning laws in an attempt to block residential development. Monroe County lost the battle in 1985 and the airport was permanently closed. Lawsuits between the two parties continued well into the late 1990s. The strip of land that was once Port Largo airport, below at far right, is now a street called Ocean Cay with high-density oceanfront property. Many residents probably have no idea that a commercial airport once operated where their houses now stand. Here's a bird's eye view of what used to be Port Largo Airport.
