O'Hare International Airport (ORD) is Chicago's primary international hub and a major transfer point for both domestic and global carriers, typically hosting full-service airlines alongside several international flag carriers. It can be perceived as mid-to-high range for fares due to extensive long-haul and business traffic. Located about 17 miles northwest of downtown, travel to the Loop usually takes 30–60 minutes by Blue Line train (fare around $3–6) or 30–60 minutes by taxi/rideshare (fares typically vary widely depending on traffic). Pros: comprehensive amenities, many nonstop options, strong public-transit links. Cons: large layout can mean long walks and occasional delays during peak weather or operations. Midway International Airport (MDW) functions as Chicago's secondary, more budget- and leisure-oriented airport, commonly serving low-cost and domestic carriers with frequent short-haul flights. It is roughly 10 miles southwest of downtown, with the Orange Line train taking about 25–35 minutes to the Loop (fare about $3–6) and taxis or rideshares usually taking 20–45 minutes depending on traffic. Pros: compact terminals and often quicker security lines; generally easier connections for domestic trips. Cons: fewer international routes and limited premium-carrier options compared with O'Hare, which can affect choice and scheduling flexibility.
