Hoping to avert a summer meltdown, federal officials said Monday they plan to make changes in airport security screening to ease growing lines in Atlanta and other U.S. cities.

Airport officials are “rightfully concerned about delays, as we are,” Peter Neffenger, chief of the Transportation Security Administration, said after meeting in Atlanta with officials from Hartsfield-Jackson International Airport and Delta Air Lines.

Neffenger said the TSA will use more overtime to boost staffing, speed up training of new screeners, deploy more dog teams that augment human workers and try new techniques and wait-line configurations to speed the process.

“It’s a production problem. What we’re doing is looking at the industrial engineering,” he said.
