Sky Harbor International AirportAuthorities are investigating a possible threat against a Southwest flight at Sky Harbor International Airport.
Flight 1184 landed as scheduled from Orange County, CA, and was moved to an isolation pad at the airport, according to Southwest spokeswoman Ashley Dillon.
All 125 passengers have been stuck inside since they landed at 7:30 p.m. and everyone, including the five-member crew, will undergo rescreening, Dillon said. All luggage will also be examined.
"There was a non-specific telephonic threat regarding Flight 1184," the FBI said in a statement.
The flight was bound for Tulsa, OK.
The FBI's Joint Terrorism Task Force and the Phoenix Police Department are on the scene conducting an investigation.
There was also a hazmat situation at John Wayne Airport in Orange County where that Southwest flight came from.
It's unclear whether the two situations are related.
The FBI in Los Angeles confirmed a bomb threat involving an airplane filled with passengers at John Wayne Airport.
Orange County sheriff's Lt. Joe Balicki said the plane was getting ready to taxi from the gate and authorities managed to stop it and isolate it.
Within the past few minutes, that plane in California was cleared to proceed and passengers are reboarding.
