Flights from Seattle to San Francisco
Seattle–San Francisco is one of the busiest short-haul corridors on the West Coast, covering roughly 1,090 kilometres with a typical block time of about an hour and forty-five minutes. Alaska Airlines dominates with high-frequency service throughout the day, while United, Delta, and American round out the schedule with multiple daily departures; Virgin America built its identity partly on this route before its absorption into Alaska. Most flights operate narrow-body jets — expect 737s and A320-family aircraft. Practically speaking, arriving passengers at SFO should note the airport's sprawling layout: domestic arrivals often land in the Harvey Milk Terminal 1 or Terminal 2, and BART connections to the city centre add roughly thirty minutes. On fares, midweek departures on Tuesday and Wednesday tend to price lower than Friday or Sunday, and shoulder seasons in late January and early November typically offer the most flexibility without peak-season pressure.
