An airport in Phoenix and one in Louisiana are the newest recipients of federal funding to help upgrade them from their former use as military bases. Phoenix-Mesa Gateway and Alexandria International Airport will share $23.7 million this year with 10 airports already receiving the funds, according to the FAA. At Alexandria, the funding will pay to overhaul an aging and outdated fuel farm. The airport supports daily commercial flights to Houston, Dallas, Memphis and Atlanta. Phoenix-Mesa will use its share of the funding to upgrade a small passenger terminal that quickly become overwhelmed when Allegiant Air began flights to the airport in late 2007. The airport recorded 120,000 passenger boardings in the first nine months of last year, due in large part to Allegiant’s flights. The Military Airport Program funding is a subset of the money available through the Airport Improvement Program.
