PHOENIX -- No explosives were found on a Southwest Airlines flight that was diverted to Phoenix Sky Harbor International Airport following a bomb threat Monday afternoon.
FBI officials said someone called in a bomb threat shortly after Southwest Airlines Flight #2675 took off from Los Angeles to Austin, Texas.
Southwest Airlines officials said the pilot made the emergency landing in Phoenix out of an abundance of caution.
According to a spokesman at NORAD, two F-16 fighter jets monitored the situation from the air as the plane was landing in Phoenix, but the jets were reportedly not considered an "escort."
The plane landed safely at Sky Harbor Airport at approximately 3:40 p.m. Monday. All 143 passengers on board swiftly deplaned via airstairs. Once on the ground, they boarded buses to be transported from the area.
The passengers were interviewed and their luggage was inspected. Bomb squad technicians along with bomb-sniffing dogs searched the plane for explosives.
Authorities are still investigating who made the threat.
The incident affected both departing and arriving flights. Flights were taking off and landing only on the south side of the airport on Sky Harbor's two south runways. Airport officials reported many delays and urged travelers to check their flight status.
The investigation also restricted roadway access on the west side of Sky Harbor until about 8:30 p.m.
