Officials say a Southwest Airlines flight traveling from Las Vegas to Milwaukee was diverted to Denver Friday night after reporting "pressurization issues."

Denver International Airport spokeswoman Laura Coale says that Flight 100, which departed Las Vegas at 6 p.m. PDT, diverted to Denver after about 90 minutes.

She tells the Denver Post that fire department crew members evaluated the passengers, but just one person was transported and that for a slip and fall injury.

She says that no one else required medical aid.

Denver's KMGH-TV reports that a Southwest statement referred to "a pressurization issue," but did not elaborate.

The statement says that 175 passengers and six crew members were aboard the Boeing 737-800, which will be taken out of service and inspected.

Meanwhile, the airline says passengers are continuing to Milwaukee on another aircraft.
