The full story
O'Hare is the larger international hub northwest of downtown; Midway lies southwest and is often simpler for some domestic routes. Both airports have direct Chicago Transit Authority rail connections, making trains useful when traffic is heavy and your accommodation is near a convenient station. With substantial luggage, young children or a late arrival, a taxi or rideshare may justify the higher cost. Follow airport signs for the current ground-transport pickup area because terminal construction and operating rules change. Check service alerts before choosing rail, then confirm whether the destination station has an elevator if step-free access matters. Allow generous time for the return journey: security, terminal transfers, weather and road congestion can all add uncertainty. Do not judge airports by straight-line distance alone; the best choice depends on flight schedule, fare and the final neighborhood.
