What TSA should do about those long airport lines

Passengers and airlines aren't getting what they paid for as long as daunting airport security lines linger, experts told CNBC's "Power Lunch" Friday.

"We've got a lot of people that aren't on the front line that probably need to be re-evaluated and thrown at this," said Gordon Bethune, former CEO of Continental Airlines. "The answer isn't throw more money at it, but use resources wisely."

The heads of the Transportation Security Administration and Homeland Security asked for patience Friday as extended wait times during the summer travel season have left passengers frustrated, spurring viral videos and social media posts.

TSA will hire more officers, increase the use of overtime, ask airlines to help with tasks that are "non-security"-related, expand canine teams and limit carry-on luggage, Homeland Security Director Jeh Johnson told NBC News reporters.

When short-distance flights require 2 to 3 hour waits, people might opt to drive, which is arguably less safe, said Seth Kaplan, managing partner at Airline Weekly. Shifting away from administrative jobs, removing full-time agents from remote locations and planning staff vacations could all help, Bethune said.

"In the end this is bad for everybody," Kaplan said. "Not only the airline industry, but also this country — what it does to productivity when you take that many hours out of people's days."
