Did you know that SFO operates on two sets of parallel runways?  During periods of low visibility, current FAA safety regulations allow aircraft to arrive side-by-side only if runways are at least 4,300 feet apart. SFO’s runways are only 750 feet apart, so aircraft must arrive single-file. This reduces the airport’s arrival rate to approximately 30 per hour.  (source:  http://www.flysfo.com/media/weather-impact)
