Chicago is served primarily by two major airports with distinct roles. O'Hare International (ORD) is the city's main international hub, typically handling a wide mix of legacy carriers and global airlines and often positioned as the pricier, full-service option; it sits about 17 miles northwest of downtown and can be reached by the CTA Blue Line in roughly 45–60 minutes (fares around transit rates) or by taxi/ride-share in 30–60 minutes depending on traffic with higher fares during peak times. Midway (MDW) is usually a budget- and low-cost-carrier–friendly airport about 10 miles southwest of the Loop; travel times are commonly 25–40 minutes by car and around 35–50 minutes via the CTA Orange Line, with generally lower fares on short-haul routes. Pros: O'Hare offers extensive international connections and full-service facilities, while Midway can be easier to navigate and quicker for domestic travel. Cons: O'Hare can be busy with longer transfer walks and congestion, and Midway has fewer long-haul options and can feel cramped at peak times.
Seattle–Tacoma International Airport (SEA) is the region’s primary international hub, handling most long-haul and domestic flights and serving legacy carriers like Alaska Airlines and major global airlines alongside some low-cost operators. Located about 14 miles (22 km) south of downtown Seattle, it can be reached by Link light rail in roughly 35–40 minutes for a low to moderate fare, by taxi or rideshare in 20–30 minutes depending on traffic, or by shuttle and car in a similar range. Fares and travel times vary with demand and time of day. Pros: comprehensive services, wide route choice and good public-transit links. Cons: can be busy at peak times and transfer distances in terminals may be long.
