Lakeland Linder Regional Airport

Lakeland Linder Regional Airport is a public airport five miles southwest of Lakeland, in Polk County, Florida. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a reliever airport.
The airport has a Federal Aviation Regulations Part 139 operating certificate allowing passenger airline flights; the current terminal facility, which opened in late 2001, was designed to host airlines with minimal modifications. Scheduled airline flights returned to the airport in June 2011, when Direct Air began service to Myrtle Beach, South Carolina, Niagara Falls, New York and Springfield, Illinois. Service ended on March 13, 2012 when Direct Air unexpectedly announced an end to operations. The charter carrier, who offered flights from Lakeland to Niagara Falls and Plattsburgh, New York; Springfield, Illinois and Myrtle Beach, South Carolina with Boeing 737 aircraft, was subject to Chapter 7 liquidation on April 12, 2012.
Annually, around March–April, the airport hosts Sun 'n Fun, a six-day Fly-in, airshow and aviation convention.
