Choosing the right Chicago airport depends entirely on your airline, your destination, and how much you hate long security lines. Picking the wrong one means extra driving time, missed connections, or paying more for rideshares.
Chicago O'Hare International Airport (ORD) sits about 18 miles northwest of downtown, serving as a massive global hub with five terminals and hundreds of direct international routes. Chicago Midway International Airport (MDW) sits just 10 miles southwest of downtown, operating out of a single compact terminal dominated by Southwest Airlines. If you're flying across the Atlantic, O'Hare is your only option. If you're flying domestically on a budget, Midway often wins.
Location and Commute Times
Distance numbers lie because Chicago traffic is brutal. O'Hare is located further out, and getting to downtown via the Kennedy Expressway (I-90) during rush hour can easily turn a 40-minute drive into a 90-minute crawl. Midway's closer proximity to the Loop via the Stevenson Expressway (I-55) usually makes for a shorter, more predictable car trip.
Public transit changes the math. The CTA Blue Line runs 24/7 straight from O'Hare's terminal area into downtown in about 45 minutes. Meanwhile, the CTA Orange Line connects Midway to downtown in roughly 30 minutes. Midway's train station is also integrated directly into the terminal, requiring a much shorter walk with heavy luggage than O'Hare's underground walk from the domestic terminals.
Airlines and Route Networks
Your airline choice usually forces your hand before you even compare the locations.
- O'Hare: Dominated by United Airlines and American Airlines, O'Hare handles heavy domestic traffic alongside global carriers flying to Europe, Asia, and South America. If you need a direct flight overseas or want access to a wide array of Star Alliance or Oneworld connections, you're flying into O'Hare.
- Midway: Southwest Airlines rules Midway, backed by smaller operations from carriers like Delta, Volaris, and Porter Airlines. While you can reach dozens of domestic cities and select near-international spots like Mexico, you won't find transatlantic flights here.
Airport Navigation and Layouts
Navigating O'Hare feels like exploring a small city. With five active terminals—including Terminal 5 for international arrivals—you might need to take the Airport Transit System (ATS) train just to switch concourses. Walking gates can take 15 to 20 minutes, and peak hours bring heavy congestion.
Midway offers the exact opposite experience. Its single terminal splits into three concourses (A, B, and C) all connected to a central security checkpoint and food hall. You can walk from the front door to your gate in under 15 minutes. Security lines move faster simply because fewer people pass through daily.
Amenities, Lounges, and Dining
O'Hare wins easily on amenities. You'll find multiple airline lounges, sprawling duty-free shops, on-site airport hotels like the Hilton ORD, and high-end local dining options such as Tortas Frontera.
Midway keeps things simple. Dining options are adequate—including local staples like Garrett Popcorn—but lounge access is virtually nonexistent outside of a small USO room. If you plan to work for hours in a quiet club before a delayed flight, O'Hare provides better infrastructure.

Common Mistakes to Avoid
Travelers frequently trip up on a few logistical details when booking Chicago flights:
- Assuming O'Hare is closer to all suburbs. If you're heading to northwest suburbs like Schaumburg or Rosemont, O'Hare is closer. If you're heading to southwest spots like Naperville or Oak Lawn, Midway is much faster.
- Forgetting about Terminal 5 transfer times at O'Hare. If you arrive on an international flight at Terminal 5, clearing customs and re-clearing security to catch a domestic connection in Terminal 1 or 3 takes substantial time.
- Relying on rideshares during peak weather. Snowstorms or heavy rain spike Uber and Lyft prices dramatically from O'Hare due to the long distance into the city. The Blue Line train bypasses highway gridlock entirely.
Frequently Asked Questions
Which Chicago airport is closer to downtown?
Midway is significantly closer to downtown Chicago, sitting about 10 miles southwest of the Loop compared to O'Hare's 18-mile northwest trek.
Can I easily transfer between O'Hare and Midway?
No. They are roughly 30 miles apart. Taking a taxi or rideshare between them can cost over $60 and take anywhere from 45 minutes to over an hour depending on traffic. Avoid booking tight connecting flights that require changing airports.
Which airport has better security wait times?
Midway generally features shorter security queues because of its smaller passenger volume. O'Hare has TSA PreCheck and CLEAR at multiple checkpoints, but its sheer size means lines can back up severely during morning and evening business travel rushes.
Is Midway cheaper to fly into than O'Hare?
Not inherently, but because Southwest operates heavily out of Midway, you'll often find competitive domestic pricing and lower baggage fee impacts if you hold a Southwest rapid rewards card. Compare base fares directly for your specific route.
