Thousands of people at San Francisco International Airport, Mineta San Jose International Airport and San Francisco Bay Oakland International Airport had to re-book flights after more than 100 between the three airports were canceled.

At San Francisco, 91 flights were cancelled by 12:30 p.m. and another 227 delayed, according to the flight-tracking company FlightAware. All were domestic flights, according to the company.
“Airport systems are functioning, and airlines report systems are back online,” San Francisco Airport spokesperson Doug Yakel wrote in an email Friday morning. “Residual impact on flights continue.”
The situation appeared to hit United Airlines and Delta Lines flights to and from and the San Francisco airport particularly hard. FlightAware stats showed United had cancelled 61 flights into and out of the airport and delayed another 130. Ten of Delta’s flights had been cancelled and 20 delayed.
The situation was not quite as dire in San Jose or in Oakland. According to FlightAware, 13 flights had been cancelled and 64 delayed in San Jose. Ten flights in and out of Oakland had been canceled and 61 delayed.
Port of Oakland spokesperson Robert Bernardo said the airport had two total cancellations on Friday night.
The tech outage meant that flights throughout all of Friday may be delayed and that others could be canceled, officials said. They urged passengers to check with the airlines on their flight status.
The outage did not have any affect on the cargo shipping operations at the Oakland Seaport, Bernardo said.
