A pipe-like item in a checked bag prompted the closure of a departure area, ticket counter and stores in the upper level of Terminal One shortly after 11:30 a.m., airport authorities said.

Two arriving Southwest Airlines flights were held at the west end of the airport rather than being allowed to roll up to the terminal.

Eventually, the owner of the luggage was located and turned out to be a managing partner in a sprinkler company, airport spokesman Marshall Lowe said.

"He had one of his products in his checked luggage," Lowe said.

The all-clear was called after about 90 minutes.

On Wednesday, Terminal Two was partially evacuated after explosive-detection equipment in the baggage screening area alerted authorities to what was believed to be some type of ammunition, officials said.

A bomb squad found two replica mortar shells that apparently were purchased from a novelty shop and didn't have any explosives in them, police said.
