ORLANDO, Fla. -- Some flight attendants and pilots are angered by an apparent double-standard of allowing Transportation and Security Administration workers to skip basic security protocol in the airport security staging area inside Orlando International Airport, according to a Local 6 News investigation.

Local 6 showed video shot by undercover cameras of seven TSA agents, some carrying shoulder bags, walking right by the metal detector and into what the industry calls the sterile area. Their bags went unchecked, the report said.

The report featured a veteran flight attendant, who was not identified, mapping out a location of an airport checkpoint that has some airline employees on edge.

"What did you see?" Local 6's Mike Holfeld asked.

"I observed a TSA agent go around the screening device instead of through (it)," the woman said. "I hate to bring this up but box cutters are small, they can slip into pockets, and for Orlando airport to have that kind of breach of security gives me great concern."

The report also showed a TSA agent in Orlando carrying a paper bag in her hand and a purse on her shoulder, walking in and never saying a word as she entered the sterile area. An agent is seen checking her badge but not her bags.

"It's unsettling to me that even the sky marshals, once they have to leave that area, have to be re-screened," the woman said.

"Local 6 has learned that this was no fluke," Holfeld said. "Nor is it unique to OIA."

A TSA officer assigned to any airport in America is allowed to bypass the screening device when returning from break, according to the report. Sometimes their badge is checked and sometimes they walk through with no questions ask, Holfeld reported.

TSA Spokesman Christopher White told Local 6 News that the practice is very secure.

"We know our TSA officers," White said in a statement. "Every shift begins with a shift meeting. We know who is working and we know who is not. Their backgrounds are checked extensively. They are trusted officers."

However, critics argue trust is not enough, according to the report.

"TSA officers casually walking into a secure area with a glance at a badge as their pass has airline employees upset," Holfeld said.

Local 6 showed the report to Rep. Ric Keller, who said he was surprised by the video evidence.

"Hopefully all those people are trustworthy but why take the risk?" Keller said.

Keller sent a letter to TSA chief Kip Hawley questioning what he calls serious gaps in the screening procedures.

"It's surprising that flight attendants and pilots and members of Congress have to walk through the metal detector yet TSA employees and some contractors don't," Keller said. "I think that's a serious loophole in our security."

Keller said his staff is still awaiting a reply from the TSA's Washington office.

"Because of our investigation, Keller will pursue changing the TSA's security checkpoint standards," Holfeld said.
