Flights from Portland to San Francisco
The 550-mile hop between Portland International (PDX) and San Francisco International (SFO) is one of the busiest short-haul corridors on the West Coast, with a typical block time of around an hour and a half that makes it a natural choice for same-day business trips. Alaska Airlines dominates the route and operates it most frequently, with American, Delta, and United all maintaining solid schedules as well; most departures use narrowbody jets like the Boeing 737 or Airbus A320 family. A practical note worth knowing: SFO's international terminal and BART station sit apart from the domestic terminals, so if you're connecting onward or heading into the city by rail, budget an extra fifteen minutes for the inter-terminal walk or AirTrain. Fares tend to soften in January and February after the holiday rush, and midweek departures — particularly Tuesday and Wednesday — typically yield better availability and lower prices than the heavily trafficked Sunday-evening and Friday-afternoon banks.
