Chicago is served by three main airports with distinct roles. O'Hare International (ORD) is the city's primary international hub and a major connecting point for legacy carriers and many global flights; it typically offers a wide range of long‑haul and domestic connections and can be perceived as mid‑to‑premium in price compared with budget-focused options. Located about 17–20 miles northwest of downtown, O'Hare is reachable by the CTA Blue Line in roughly 45–50 minutes, taxis or rideshares in 30–60 minutes depending on traffic (fares vary), and several shuttle and express services. Pros: extensive schedules and amenities; cons: busy terminals and occasional congestion. Midway Airport (MDW) functions more as a domestic and low‑cost carrier base, often used for short‑haul flights around the U.S. and by discount airlines; fares can feel more budget‑friendly on many routes, especially point‑to‑point. Midway sits roughly 10 miles southwest of the Loop and is typically a 20–35 minute drive in normal traffic. Public transit includes the CTA Orange Line, taking about 25–30 minutes to downtown with economical fares; shuttles and taxis are also common. Pros: compact layout and faster security lines; cons: fewer international options and smaller amenities than the larger hub. General travel notes: choose O'Hare when you need international connections or more flight options, and consider Midway for quicker domestic hops and potentially lower fares. Both airports have solid public transit links, although travel times and costs can vary with time of day and luggage needs.
