Could our national nightmare of long airport lines finally be over? The Transportation Security Administration (TSA) announced on Tuesday that it is taking steps to help end it: by getting rid of human agents and adding automation.

The TSA and American Airlines will be using CT scanners on carry-on bags at Phoenix’s Sky Harbor International Airport in a pilot program set to begin later this year. This is already what happens to your checked luggage: every bag is scanned and inspected by a computer, after which human security officers manually examine bags flagged as suspicious (unless, of course, there’s another computer glitch, which happened in Phoenix just two months ago).

American Airlines will also be implementing automated screening lanes in airports in Chicago, Dallas/Fort Worth, Los Angeles, and Miami, which the TSA says could cut down time spent in lines by 30 percent. Delta is running a similar program with the TSA in Atlanta’s Hartsfield-Jackson International Airport.

If all goes well, the TSA said, this could be expanded to other airports, which would mean faster security lines and fewer agents needed. That’s crucial during a summer when security line wait times have skyrocketed and both consumers and airport authorities are reaching a “breaking point” with the TSA. Some cities have threatened to replace TSA agents with private companies. The TSA has blamed the lines on a lack of funding and an increase in travelers, asking Congress for more money to hire new officers and pay existing ones overtime. If the CT scanners and automated screening lines prove effective, those officers may not be needed after all.
