The St. Petersburg-Clearwater International Airport is located on State Route 686, Roosevelt Boulevard, just west of I-275, six miles east of Clearwater and five miles north of St. Petersburg.

Constructed on the site of the Pinellas County Municipal Airport, Pinellas Army Airfield became operational in August 1942. Serving as a sub-base to Sarasota Army Airfield, this site operated a technical training school and provided training for replacement fighter pilots and air crews. As many as 1,500 Third Army Air Force trainees, flying P-40 Warhawks and P-51 Mustangs, could be found at this site at any one time. General James H. Howard, WWII Medal of Honor recipient and the last wartime base commander, is honored through an exhibit in the terminal of St. Petersburg-Clearwater International Airport, now on this site.
