OMAHA, Neb. (AP) — A Southwest Airlines flight headed to Connecticut made an emergency landing here after a person who missed the flight made a bomb threat, an airline spokeswoman said Sunday.

No explosives were found after the plane landed Saturday night, and the 137 passengers on Flight 1018 continued on to Hartford, Conn., after the unexpected layover of just over three hours, spokeswoman Christi Day said.

Day said the passenger who missed the flight made a statement about a bag and then made a bomb threat specific to Flight 1018.

Passengers were bused to a field maintenance building while security personnel using bomb-sniffing dogs searched passenger and baggage compartments.
