I hope we can finally see some improvements at SFO. The fact that the slightest impact on visibility can cause 4-5 hour long delays is ridiculous. the SF government has tirelessly blocked all attempts to fix the runways so that planes can land in visibility conditions (fog/rain) with the promise that technology would solve the problem.

The problem isn’t the airport. It’s the lateral separation requirements for IFR aircraft on the ILS. Most airliners can land in 0-0, but you can’t do 0-0 landings on parallel runways with the ILS because of lateral separation requirements. There is also flow control that is from the FAA — under IFR the acceptance rates are reduced. The short answer isn’t that SFO isn’t “upgraded” but the rate of aircraft acceptance is reduced under low visibility conditions per the FAA — and for good reason, separation of aircraft.
