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.
San Francisco International Airport (SFO) serves as the Bay Area’s primary international and domestic gateway, functioning as a major hub for full-service carriers and international connections while also handling some low-cost and regional flights. Located about 13 miles south of downtown San Francisco, it’s typically reachable by BART in roughly 30–40 minutes (fares usually in a moderate range), by airport shuttle or rideshare in 25–45 minutes depending on traffic (costs vary), and by taxi in about the same time at higher cost. Pros include extensive international facilities, numerous lounges and frequent nonstop routes; cons can be busy terminals and occasional heavy traffic to/from the city during peak hours.
