The wet and cloudy weather has prompted the Federal Aviation Administration to turn on San Francisco International Airport's “metering lights.”
The FAA instituted at 9 a.m. a program that limits the number of planes coming and leaving SFO because of the low clouds, said Michael Brown, an airport duty manager.
Average delays were forecasted at 90 minutes, but Brown said they were much more likely to be 60 minutes if at all. The program aims to prevent flights from circling airports in airborne holding patterns, he said.
“We can only land on one our parallel runways at one time,” Brown said. “It's like the metering lights on a freeway on-ramp. It slows down the traffic coming onto the freeway to a level that the freeway can accept.”
Brown recommended passengers call ahead to check the status of their flights.
