PHOENIX - Southwest Airlines officials say a flight from Phoenix to Sacramento had to be diverted Monday night after a smoke alarm was triggered in the bathroom.
According to the Flight Aware, the flight left Sky Harbor Airport at approximately 5:30 p.m. and arrived in Las Vegas about an hour later.
Southwest spokesman Dan Lansing said in addition to five crew members, there were 140 passengers on board.
According to Lansing, while en route to Sacramento, a smoke alarm was triggered in a bathroom at the back of the plane.
One of the pilots checked for smoke, but found nothing.
Lansing said the flight captain decided to land at McCarren International Airport in Las Vegas.
The pilot declared an emergency and landed safely.
Officials said after the plane landed, passengers got off and fire crews went in to check for any signs of fire or smoke.
Lansing said they weren't able to find anything.
The passengers were switched to a new aircraft which was expected to land in Sacramento by 10:30 p.m.
