Airlines and passengers are being warned that weeks of necessary maintenance at San Francisco International Airport will result in flight delays and cancellations. 

SFO officials notified airlines this week that one of the airport's three runways will be closed for 20 days in September. 

Due to the loss of runway capacity, airport spokesman Doug Yakel said that "delays could run around 90 minutes on average."

Travelers booking flights from September 7 to 27 are encouraged to look for early departure times.

"Delays and cancellations will begin starting at 9 a.m. everyday," Yakel said. "If you can get a flight out of SFO before that, you've got a good shot of it being on time."

The airport may have to reduce the overall number of flights by 10 percent while crews work on the runway. 

The work will add a new "base layer" to a 1,900-foot section of Runway 28L, Yakel said. 

The project is scheduled for September because of the low likelihood of rain and to avoid interfering with the busier summer season.
