SheltAir Aviation Services expanded its Florida FBO stable to seven and total count to eight with the acquisition of Sowell Aviation Services at Panama City-Bay County International Airport. The purchase includes 40,000 sq ft of FBO terminal, office and hangar space. When Panama City moves the airport to a new location in a few years, SheltAir plans to build an expanded FBO to take advantage of growing aviation opportunities in the Florida Panhandle, according to SheltAir COO Ed Zwirn.
