Federal security screening is returning to a small West Tennessee airport, a needed upgrade as passenger traffic is expected to increase with new flights to Atlanta and a planned Ford Motor Co. electric truck factory coming to the region, officials said. The Transportation Security Administration plans to resume passenger screening service at McKellar-Sipes Regional Airport in Jackson, U.S. Rep. David Kustoff said Wednesday. The airport has not had TSA service in 13 years because of a decrease in passenger count and TSA budget constraints, said Steve Smith, the airport’s executive director.
