"The crew members also had to manually pressurize the cabin," told the Alaska Airlines spokesperson Bobbie Egan in an email. Egan told the oxygen masks didn't deploy.
The aircraft was lowered to 10,000 feet and had been necessary to be diverted to San Jose, California. The flight, with one hundred thirty one travellers and five crew members on the board of the airplane, landed safely at 7:48 a.m. PT.
Support professionals are still working to define the reason of the issues.
Egan also told they work to put some travellers on other flights out of San Francisco and Oakland. The Alaska Airlines Company is also substituting a larger airplane for its noon flight out of San Jose to accommodate other travellers.
