St. Petersburg Clearwater International Airport — Pinellas Park, United States

St. Petersburg-Clearwater International Airport, coded PIE, occupies a site in Pinellas Park that traces back to military aviation training during the Second World War before transitioning to civilian use and eventually becoming a stronghold for low-cost leisure carriers, most notably Allegiant Air, which built much of its route network around smaller secondary airports like this one. PIE functions as a secondary option to the larger Tampa International Airport across the bay, drawing travelers headed specifically toward the beach communities of Pinellas County, including Clearwater Beach, which regularly ranks among the top-rated beaches in the United States. The airport's relatively small scale and streamlined layout appeal to leisure travelers seeking to avoid the longer walks and larger crowds typical of bigger regional hubs. Seasonal demand rises noticeably during winter months as travelers from colder northern states seek warmth along Florida's Gulf Coast beaches near PIE.
