Passengers put up with endless hassles from the Transportation Security Administration in hopes it all keeps them safe. So after 11 people got past a JFK checkpoint Monday without being screened, you’d think heads would roll. Hah!

The 11 got through, apparently, because TSA staffers left a security lane open but unmanned. Three set off a metal-detector alarm and still walked on. And TSA didn’t tell Port Authority cops for two hours.

Airport police from around the country call the flap “unconscionable.” TSA has taken its “eye off the ball,” fumed American Alliance of Airport Police Officers co-founder Marshall McClain. Uh, ya think?

True, most of the 11 were tracked down and found not to be threats . . . after they landed.

The agency’s official statement on what comes next: “Once our review is complete, TSA will discipline and retrain employees.” Oh, and it has ID’d the responsible workers and “appropriate action is being taken.”

Retraining. Appropriate action. How about fired? Sorry, no: TSA staff are a protected branch of the American Federation of Government Employees, one with the hilarious motto: “Stronger Union, Safer Skies.”

Private-sector workers who mess up so badly as to put lives in jeopardy would be gone in a heartbeat. Heck, they’d be fired for far less serious breaches.

Somewhere along the road to making America great again, Mr. President, how about privatizing the damn TSA to end all the maddening “security theater”?
