Southwest Airlines spokesman Paul Flaningan says a fuel valve problem prompted the crew of Flight 2879 to declare an emergency. The Boeing 737 was diverted to Omaha's Eppley Airfield and landed around 9:30 p.m. Tuesday.
Flaningan says the plane landed without incident. It was carrying 109 passengers and five crew members from Denver to Kansas City International Airport.
He says the passengers boarded another plane and arrived in Kansas City, Mo., about two hours later than their original schedule.
