A blackout in Southern California on Friday reportedly left around 28,000 customers without power and grounded all flights at Orange County’s John Wayne Airport through 7 a.m. Saturday.

Flights arriving at the airport after 7:30 p.m. Friday were diverted to other airports and all departing flights were canceled, an airport spokesperson told The Los Angeles Times.

“People are not happy, but they’re rolling with it. They realize we’re doing the best we can,” the spokesperson said.
