NEWARK, N.J. (CBSNewYork) — The Port Authority of New York and New Jersey is giving the Transportation Security Administration an ultimatum on dealing with long lines at airports.

CBS2’s Christine Sloan reported the Port Authority is warning the TSA in a letter it will be replaced by a private security force.

“We can no longer tolerate the continuing inadequacy of the TSA passenger services,” the letter reads.

The letter states the long waits at John F. Kennedy, LaGuardia and Newark Liberty International Airports are “prompting angry complaints from passengers, terminal operators, and airlines alike … citing inconvenience, delayed flights and missed flight connections.”

Passengers have been waiting up to an hour in lines at security checkpoints.

“They’re pretty long,” one traveler said.

Travel expert Peter Trabucco said travelers should not be concerned if airports turn to private security forces.

“Not really, because the processes and the protocols are all set up,” Trabucco said. “They’re going to be doing the same, that’s why the lines are all long because of terrorism.”

Trabucco said the goal of privatization is to cut costs.

“Time would tell if it would work or not. It depends on the company, it depends on how serious they are. Some are good, some are bad,” Trabucco said. “I still feel the TSA itself has a very, very tough job.”

The TSA said it “will directly respond to the Port Authority.”

However, the agency is trying to get more money to hire extra screeners and pushing “pre-check,” a program passengers can sign up for that screens them before they travel.

“I can keep my shoes on. I believe I can keep my computer in my backpack. It’s easier with children,” traveler Denise Suri said.
