Alaska Airlines flight diverts after mid-air electrical problems

A Seattle-bound Alaska Airlines flight made an emergency landing in California early Wednesday after the plane experienced multiple electric issues.

Flight 539 from Ontario, Calif., was en route to Seattle when the Boeing 737-400 aircraft experienced problems while climbing to cruising altitude, the Seattle-based airline confirmed.


"The crew also had to manually pressurize the cabin," Alaska Airlines spokesperson Bobbie Egan told NBC News in an e-mail. Egan said the oxygen masks did not deploy.

The plane was lowered to 10,000 feet and diverted to San Jose, Calif. The flight, with 131 passengers and five crewmembers onboard, landed safely at 7:48 a.m. PT.

Maintenance technicians are working to determine the cause of the problems.

Egan said they are working to put some passengers on other flights out of San Francisco and Oakland. The airline is also substituting a larger aircraft for its noon flight out of San Jose to accommodate other passengers.
