Search FlightsFlying from the heart of the Midwest to the iconic hills of Northern California represents one of the most popular transcontinental routes in the United States today. Spanning roughly 1,850 miles across the country's midsection, this journey takes you from the bustling skyscrapers and deep-dish pizza of Chicago to the foggy charm and tech-driven pulse of San Francisco in just about four and a half hours. Whether you are traveling for a high-stakes business meeting in the financial district or planning a leisurely weekend exploring the historic piers of Fisherman's Wharf, these two major global hubs are seamlessly connected by dozens of daily non-stop flights from several major carriers.
Travel Tips
To maximize your comfort on this mid-range flight, consider booking a window seat on the right side of the aircraft when flying westbound from Chicago; on clear days, you may catch breathtaking views of the Rocky Mountains or the snowy peaks of the Sierra Nevada range. Because Chicago O'Hare is notorious for weather-related delays, especially during winter snowstorms or intense summer thunderstorms, it is wise to always check your flight status before leaving for the airport and consider an early morning departure to avoid the cascading delays that can build up later in the day. Once you land at SFO, skip the expensive rideshares and utilize the BART (Bay Area Rapid Transit) system located in the International Terminal for a cost-effective and traffic-free commute directly into downtown San Francisco.
Airport Information
Chicago (ORD)
Chicago O'Hare International Airport (ORD) is a primary global gateway known for its massive scale and four distinct terminals. As a major hub for both United and American Airlines, it offers extensive lounge options and high-end dining across its concourses. Navigating O'Hare is made easier by the automated people mover system, but travelers should still arrive at least two hours early due to the sheer volume of passengers moving through security checkpoints daily.
San Francisco (SFO)
San Francisco International Airport (SFO) is located about 13 miles south of downtown and serves as a premier international terminal. It is famous for its 'Wag Brigade' of therapy animals and the SFO Museum, which features rotating art exhibitions throughout the terminals. SFO is highly committed to sustainability, featuring LEED-certified buildings and plenty of hydration stations, making it one of the most modern and eco-friendly airports in the country.
Seasonal Pricing Patterns
Generally, the most expensive times to fly from ORD to SFO coincide with the peak summer travel months of June and July, as well as the major holiday weeks in late November and December. For the best deals, savvy travelers should look for flights in the shoulder seasons of late January and February, when Midwesterners often seek a break from the cold, but demand for business travel is slightly lower. Mid-week departures on Tuesdays and Wednesdays typically offer more competitive pricing compared to peak Friday or Sunday flights.
