Terminal One at Lindbergh Field is back open after a bomb-sniffing dog alerts officials to a suspicious bag on Friday morning.
The bag was left by a disabled cart inside the terminal at the Alaska Airlines booth, police said. Both United and Alaskan Airlines had to close their ticket counters for a short period of time.
Bomb squad detectives say the bag was full of clothes, no explosives were found inside.
Police had to divert traffic from the terminal for a short-time and customers inside the terminal were kept by baggage claim, while the bomb-squad did their investigation.
If you are flying out of Lindbergh Field on Friday, the airport suggests calling your airline first to check for delays.
