Midway Airport is rarely fully closed, but individual flights are delayed or cancelled regularly

Chicago Midway International Airport (MDW) operates year-round and does not shut down for extended periods. However, individual flights get delayed or cancelled almost daily due to weather, mechanical issues, air traffic congestion, or staffing. A full airport closure is extremely rare — it happens only during severe weather events like blizzards or ice storms that make the runways unsafe, and even then it usually lasts hours, not days.

If you are trying to reach someone at Midway, book a flight there, or pick someone up, you need to know whether your specific flight is affected, not whether the airport itself is open. The airport's website and the airline's app will tell you the status of your flight in real time.

Key Takeaways

  • Midway Airport operates every day of the year and full closures are extremely rare; check your airline's app or website instead to see if your specific flight is delayed or cancelled.
  • The airport's official status page at flychicago.com shows weather conditions and any operational disruptions affecting all flights.
  • Your airline's website or mobile app displays your flight's current status, gate number, and any changes within minutes of them happening.
  • Winter weather, especially snow and ice, causes the most delays and cancellations at Midway, typically between November and March.
  • If your flight is cancelled, contact your airline directly by phone or app — do not rely on email or social media for rebooking.

How to check if your flight is delayed or cancelled

Go to your airline's website or open its mobile app and enter your confirmation number and last name, or search for your flight by date and route. The app will show you the current status — on time, delayed, or cancelled — and update it automatically as conditions change. This is faster and more accurate than calling the airport, because the airline controls the flight, not Midway itself.

If you do not have a confirmation number, you can search by flight number and date on the airline's site. Most airlines update flight status every 15 to 30 minutes during the day. If you are checking very early in the morning or late at night, the status may not update until closer to departure time.

You can also text your airline — most carriers offer SMS alerts if you have booked through their website. Sign up for notifications and the airline will text you if your flight changes.

Check Midway's official airport status

Visit flychicago.com, the official website for Chicago's airports (Midway and O'Hare). The homepage displays current weather conditions, any runway closures, and whether the airport is operating normally. If there is a weather event or mechanical issue affecting multiple flights, it will be posted there.

The site also lists which airlines operate at Midway and links to their websites. If you need to reach the airport's main information line, the number is 773-838-0600, but they will direct you to your airline for flight-specific questions.

Winter weather causes the most disruptions

Heavy snow, ice, and freezing rain are the leading reasons for delays and cancellations at Midway. Chicago winters bring these conditions regularly from November through March. When snow accumulates on the runways or taxiways, the airport must close them temporarily to clear them, which backs up all flights.

If winter weather is forecast for your travel day, check your flight status the night before and the morning of your flight. Airlines sometimes cancel flights 12 to 24 hours in advance if they know conditions will be severe. Arriving at the airport extra early on snowy days also helps, because security lines and check-in move slower when the airport is busy.

What to do if your flight is cancelled

Contact your airline when ready — do not wait. Call the phone number on your ticket, use the airline's app, or go to the airline's website and select "manage my booking." Most airlines let you rebook on the next available flight to your destination at no extra charge if the cancellation was their fault or due to weather.

If the airline cannot get you to your destination the same day, ask whether they will pay for a hotel room and meals. Policies vary by airline and by reason for cancellation. If the flight was cancelled due to weather, the airline is usually not required to pay for hotels, but many do anyway. If it was cancelled due to a mechanical issue or staffing problem, the airline is more likely to cover costs.

Keep your boarding pass and any receipts for meals or transportation. If you paid for the flight with a credit card, you may also be able to dispute the charge or file a claim with the card issuer if the airline does not rebook you within a reasonable time.

Midway versus O'Hare — which airport is more likely to close

Chicago has two major airports: Midway (MDW) on the southwest side and O'Hare (ORD) on the northwest side. O'Hare is larger and handles more flights, so it experiences more delays overall. Midway is smaller and sometimes closes to traffic briefly during severe weather because it has fewer runways and less room to divert planes.

If you are booking a flight to or from Chicago and want to avoid delays, neither airport is significantly better than the other during winter. Both are affected by the same weather. Your choice should depend on which airline you prefer and which airport is closer to your home or destination.
