"We currently do not believe a creditable threat existed to the flight," said Dave S. Joly, a spokesman for the FBI Denver office. "Out of an abundance of caution security protocols were implemented and safety measures were closely followed."
Flight 1500, with 151 passengers, had flown to Colorado from Detroit, landing at about 4:39 p.m. without incident.
The FBI did not specify the nature of the threat, but the Denver Post reported that a threatening note had been found on the plane.
The plane, a 737, was diverted to a remote portion of the airfield so authorities could investigate.
"The FBI Denver Division and multiple other agencies responded to a security concern on Delta Flight 1500 this evening at Denver International Airport," Joly said in a statement. "Passengers, crew members and the aircraft were rescreened and interviews were conducted."
Around 10 p.m., more than five hours after it began, the incident was over and passengers were allowed to reclaim their luggage and continue with their travel plans.
