An American Airlines flight was diverted Thursday morning to Lambert-St. Louis International Airport.
Fox 2 aerial footage showed luggage from the plane being spread out on the tarmac. A dog was being led around the luggage. After the luggage was sniffed, it was placed on luggage carts.
The trip originally was scheduled to be a non-stop flight to Phoenix. No reason has been given for the security check. The plane was scheduled to depart Lambert at 11 a.m. with a 1:53 p.m. arrival in Phoenix.
Passengers were taken off the plane around 9:05 a.m. American Airlines said there were 113 passengers and five crew members were on the plane. Police K-9 units boarded the plane after it was cleared of passengers.
Other air traffic was not affected by the situation.
