Chicago is served by two main airports with different roles. O’Hare International (ORD) is the primary international and connecting hub, typically handling most long-haul and legacy-carrier flights (United, American, and international airlines) and can be pricier on average than secondary airports. It’s about 17–20 miles northwest of downtown (roughly 30–60 minutes by car depending on traffic). Transit options include the Blue Line ’L’ (about 45–60 minutes, low single-digit fares), express shuttles, taxis and rideshares (30–90 USD typical range), and airport shuttles. Pros: extensive route network and frequent services; cons: large terminals, potential for long walks and delays during peak times. Midway International (MDW) functions more as a domestic and budget-oriented airport, commonly serving low-cost carriers such as Southwest plus some domestic legacy flights. Located roughly 10 miles southwest of the Loop (around 20–40 minutes by car), it’s often perceived as more affordable and quicker to navigate than O’Hare. Public transit includes the Orange Line ’L’ (about 25–40 minutes, modest fare), plus buses, taxis and rideshares (usually lower transfer costs than O’Hare). Pros: compact layout and faster processing for many domestic trips; cons: fewer international routes and more limited long-haul options.

Bangkok is served primarily by two airports with different roles. Suvarnabhumi (BKK) is the international hub for long-haul and full-service carriers, typically handling most intercontinental and many regional flights; it’s about 30–40 km east of central Bangkok, usually a 30–60 minute drive depending on traffic. Options include the Airport Rail Link (about 25–30 minutes to the city for moderate fares), taxis and ride-hailing (30–60 minutes, fares vary with tolls), and airport buses. Don Mueang (DMK) functions as a budget and domestic gateway, often used by low-cost carriers and regional services; it’s roughly 20–25 km north of the center, commonly a 25–45 minute drive. Bus, commuter rail connections and taxis are available with lower typical fares than premium airport transfers. Pros: Suvarnabhumi offers more international connections and amenities; Don Mueang can be cheaper and quicker for low-cost carriers. Cons: Both can be affected by Bangkok’s heavy road traffic, and transfers between the two airports may take well over an hour.
