Cheap Flights from Denver to San Francisco — $276

Denver International Airport (DEN) is the primary international gateway for the Denver metro area and a significant U.S. connecting hub, handling a mix of legacy carriers and low-cost airlines — Delta, United, Southwest and frontier carriers are commonly present. Located about 25 miles (roughly 35–45 minutes by car, depending on traffic) northeast of downtown, it’s accessible by the A Line commuter rail (about 37–40 minutes to Union Station) and airport shuttles, taxis or rideshares (typically 40–60 minutes; fares vary by service). Flights can be competitively priced thanks to strong low-cost competition, though transcontinental and international legs may cost more. Pros: extensive route network, modern facilities and year-round operations. Cons: long transfer distances between gates, potential for weather-related delays and longer ground transfer times to downtown.
