Typical roundtrip economy fares range from $150 to $350 when booked 3–8 weeks in advance, though prices climb during Presidents' Day weekend and Valentine’s Day.

Chicago (All Airports) (CHIA) refers to the city's primary commercial airports — O'Hare International Airport (ORD) and Midway International Airport (MDW) — plus nearby access points used by travelers. In February, most nonstop and one-stop itineraries to San Francisco International Airport (SFO) originate from ORD, with some budget or regional connections operating out of MDW. When searching, include both ORD and MDW or search 'Chicago to SFO' to capture all available flight options and deals.
A nonstop flight from Chicago (typically ORD) to San Francisco International Airport (SFO) averages 4 hours and 15 minutes to 4 hours and 40 minutes in February, depending on winds and routing. Expect slightly shorter westbound times and variable schedules; factor in the 2-hour time difference (Chicago CST to San Francisco PST) when planning arrival and transfers. Check carrier schedules for exact flight durations and buffers for weather-related delays.
February often yields competitive fares on the Chicago to San Francisco route due to lower leisure demand after the holiday season, though prices can spike around Presidents' Day weekend and Valentine's Day. Airlines and OTAs commonly release February sale fares 4–8 weeks in advance; signing up for fare alerts and checking mid-week can uncover roundtrips in the $150–$300 range in economy. For best savings, be flexible on dates and consider red-eye or midweek departures.
Chicago winter weather can cause delays or cancellations, especially during snow, ice, or strong winds, impacting departures from ORD or MDW. San Francisco usually has cool, wet winter conditions but rarely experiences severe airline disruptions; however, storms can affect inbound aircraft and connections. Allow extra connection time, monitor airline notifications, and consider travel protection when booking February flights.
To find the lowest fares in February, search flexible date calendars, mix-and-match one-way tickets, and consider low-cost carriers or midweek departures. Use fare alerts, check nearby airports, and consider short layovers; flights with one connection via Denver, Phoenix, or Dallas often reduce cost but increase travel time. Compare baggage fees and total door-to-door travel time before booking to ensure a genuine saving.

If your itinerary includes the East Bay or Silicon Valley, consider landing at or transferring through Oakland (OAK) or San Jose (SJC) for convenience.

February can be one of the better months to find lower fares on the Chicago to San Francisco route outside of holiday peaks. For the best prices, book flights 3–8 weeks in advance and favor midweek departures (Tuesdays–Thursdays). Avoid Presidents' Day weekend unless you need the long weekend, as fares and demand increase.
