The City of Pensacola is updating its master plan for the Pensacola International Airport and is now developing a 20-year master plan for the airport. The number of passenger flights is steadily climbing, and the facility is also growing with the expansion of ST Engineering. The city plans to hold a public workshop tomorrow from 5:30 p.m. to 8:30 p.m at the Vickrey Community Center, 2130 Summit Boulevard. Airport management will provide information on the master planning process and the proposed development.
