Aguilar said TSA alerts are circulated on a daily basis to make sure they agency's staff has access to the latest security concerns, even if they later prove false or inconclusive.

“We get these all the time,” he said. “Almost all the time they prove false.”

TSA regional spokeswoman Jennifer Peppin said her agency has issued more than 90 bulletins in the past six months.

“It is really a standard way of communicating that information to the people out there on the front line,” Peppin said.
