Nebraska ? A Southwest Airlines flight headed to Connecticut made an emergency landing Saturday in Omaha 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 in Las Vegas made a statement about a bag and then made a bomb threat specific to Flight 1018. Day said she didn’t know whether the threat was made to a gate agent in Las Vegas or by telephone.

Day had no additional information on the passenger.

The threat was made at 8:40 p.m. CST Saturday, Day said, and the plane landed in Omaha about an hour later.
