Midway Airport is not closing, but service changes happen regularly

Chicago's Midway International Airport (MDW) remains open and operational. The airport does not have plans to shut down permanently. However, Midway—like all major airports—undergoes maintenance, runway work, terminal renovations, and seasonal adjustments that can affect flight schedules and gate availability on specific dates.

If you are asking because your flight was cancelled or delayed, the cause is usually temporary: a runway closure for resurfacing, a terminal section under renovation, weather, or staffing at your airline. These are different from the airport itself closing.

Key Takeaways

  • Midway Airport operates year-round and has no announced permanent closure.
  • Temporary runway or taxiway closures for maintenance can affect flight schedules for days or weeks at a time.
  • Terminal renovations and gate work happen regularly but do not shut down the entire airport.
  • You can check Midway's official website or call the airport directly to confirm whether a specific closure affects your travel date.
  • Your airline's website will show cancellations or delays tied to airport work before you arrive.

Why Midway has temporary closures

Midway operates two parallel runways. When one runway closes for maintenance—typically for resurfacing, lighting repairs, or drainage work—the airport continues to function on the other runway, but with reduced capacity. This can mean fewer flights per hour and longer delays during peak times.

These runway closures are planned months in advance and published on the airport's website. They usually last between one and four weeks. The airport coordinates with airlines so they can adjust schedules, but some flights still get delayed or moved to different times.

Terminal work is separate from runway closures. Midway has been renovating its terminals in phases over several years. Construction happens in sections so that gates remain open, but it can affect parking, walkways, and baggage claim areas.

How to check if Midway has a closure on your travel date

Visit the official Midway Airport website (flymidway.com) and look for the "Airport Status" or "Construction" section. This page lists active runway closures, their dates, and expected impact on operations.

You can also call Midway's main information line at 773-838-0600 to ask whether a specific closure affects your flight date. Have your flight number and airline ready.

Your airline's website is the fastest way to see if your specific flight is affected. If Midway has a runway closure on your travel date, your airline will have already adjusted schedules or posted a delay notice in your booking.

What happens to flights during a runway closure

When one runway closes, the airport does not cancel all flights. Instead, it reduces the number of flights it can handle per hour. Airlines prioritize their own flights and may consolidate smaller routes or move flights to earlier or later times.

Delays are common during these periods because planes must wait longer for takeoff and landing slots. If your flight is scheduled during a runway closure window, expect a delay of 30 minutes to two hours, depending on how busy the airport is that day.

Some airlines cancel flights on routes with low demand rather than operate them with delays. If your flight is cancelled due to a runway closure, your airline must rebook you on another flight at no extra cost or refund your ticket.

Midway versus O'Hare: which airport affects your flight

Chicago has two major commercial airports: Midway (MDW) and O'Hare (ORD). If your flight is from or to Chicago, confirm which airport is on your ticket. A closure at O'Hare will not affect Midway flights, and vice versa.

Midway is smaller and handles fewer flights than O'Hare, so it is less likely to have major disruptions. However, because it has only two runways, a closure at Midway has a bigger proportional impact on operations than a similar closure at O'Hare, which has four runways.

What to do if your flight is delayed or cancelled

Check your airline's website or app first. If the delay or cancellation is due to a Midway runway closure, your airline will have posted that reason in your booking.

If your flight is cancelled, you have the right to a refund or a rebooking on the next available flight. If the cancellation is due to airport maintenance (not weather or mechanical failure), the airline still must offer one of these options.

If you are already at the airport, go to your airline's ticket counter or gate agent. They can rebook you when ready or process a refund. Do not wait for a phone call—go in person if possible.
