Officials gave the all-clear after a white substance was found onboard a flight at Fort Lauderdale-Hollywood International Airport.
Southwest Airlines said in a statement that the flight crew discovered the powder substance under a seat Sunday during a routine check after the plane had landed in Fort Lauderdale from Baltimore.
The crew contacted local authorities, who then came to inspect the substance.
No passengers were on board at the time.
The airline says after inspecting the aircraft, authorities determined the substance wasn't harmful and the plane was then cleared for takeoff.
