You’re standing on the orange line, or maybe you just pulled up to the curb at 5700 South Cicero Avenue, and that familiar knot starts tightening in your stomach. You start wondering if Midway airport security wait times are going to ruin your morning. It’s a valid fear. Chicago Midway (MDW) is a weird beast because it’s basically one giant hallway leading to a single massive security checkpoint. Unlike O'Hare, where you can scurry between different terminals to find a shorter line, at Midway, you’re committed. If that bridge over Cicero Avenue is backed up, you’re stuck in the thick of it.
Honestly, people underestimate this place. Because it’s smaller than ORD, travelers assume it’s a breeze. It’s not. Not always.
Midway is a major fortress for Southwest Airlines. That means when Southwest has a hub-and-spoke wave of flights coming in or out, the security checkpoint transforms from a ghost town into a chaotic sea of rolling suitcases and discarded shoes in about fifteen minutes flat. I’ve seen the line move like a well-oiled machine, and I’ve seen it stretch so far back into the parking garage bridge that people start looking visibly panicked.
The Reality of the "Bridge" and How It Affects Your Flight
If you’ve flown out of MDW, you know the bridge. It’s that long, glass-walled walkway that connects the parking and transport hub to the actual terminal. It’s also the primary "overflow" zone for the TSA. When you ask about Midway airport security wait times, what you’re really asking is: "How far back on the bridge does the line go today?"
TSA officially suggests arriving two hours early. That feels like a lot for a "small" airport. But here’s the thing: Midway’s layout is uniquely vulnerable to surges. Since all three concourses (A, B, and C) funnel through one central security screening area, there is no "secret" checkpoint. You can't just walk to Terminal 3 to avoid a crowd like you can at O'Hare.
Wait times fluctuate wildly. On a random Tuesday at 10:00 AM, you might breeze through in 6 minutes. But on a Monday morning at 5:30 AM? You’re looking at 35 to 45 minutes, easily. Business travelers in Chicago are a different breed; they show up early, they have TSA PreCheck, and they move fast, but the sheer volume of them can still clog the arteries of the airport.
Why the "Average" Wait Time is a Lie
Data from the TSA and third-party trackers often cite an average wait time of around 12 to 15 minutes for Midway.
That’s misleading.
Averages don't matter when you're the one standing behind a family of six trying to figure out if their yogurt counts as a liquid. The "peak" times are what kill your schedule. Typically, these peaks hit between 5:00 AM and 8:00 AM, and again from 2:00 PM to 5:00 PM. This is when the business commuters and the weekend warriors collide. If you are flying during these windows, add 20 minutes to whatever your app is telling you.
PreCheck, CLEAR, and the "Secret" Efficiency of MDW
Is TSA PreCheck worth it at Midway? Absolutely. It’s probably the single best investment for a frequent Chicago traveler. The PreCheck line at Midway is located on the far left of the security entrance. Even when the general line is snaking down the bridge, the PreCheck line usually stays within the main atrium.
But there’s a nuance here.
Sometimes, if the airport is truly slammed, TSA will do "PreCheck Lite." This happens when the dedicated lane isn't enough to handle the volume, or they’re short-staffed. You might get to keep your shoes on, but you still have to take your laptop out. It’s annoying, but it’s still faster than the "standard" misery.
Then there’s CLEAR. Midway does have CLEAR pods. If you have both CLEAR and PreCheck, you are basically a god at MDW. You skip the document check, move to the front of the PreCheck line, and you're usually through in under 5 minutes. Without PreCheck, CLEAR still saves you time, but you're still stuck taking your belt off like everyone else.
The Impact of Modernization
Over the last few years, the Chicago Department of Aviation has poured a lot of money into the "Midway Modernization Program." This wasn't just about adding a Shake Shack (though that was a great call). They actually expanded the security checkpoint area. They widened the bridge and increased the number of lanes.
This has helped. Sorta.

The physical space is better, but the bottleneck is often staffing rather than square footage. If the TSA is running four lanes instead of eight, the newest architecture in the world won't save you.
Real-World Factors That Spike Wait Times
- Weather in the Midwest: This is a big one. When O'Hare starts canceling flights due to a lake-effect snowstorm, people scramble to rebook through Midway. Suddenly, the passenger volume spikes beyond what the daily staff was prepared for.
- Sporting Events: Never underestimate the power of a Bears game or a major convention at McCormick Place. When 20,000 people all try to leave Chicago on a Monday morning after a big event, the Midway airport security wait times reflect that reality immediately.
- The Southwest Factor: Since Southwest doesn't do assigned seating, people are incentivized to get to the gate early. This creates a "front-loading" effect where everyone hits security much earlier than they would for a United or Delta flight.
How to Check Times in Real-Time Without Getting Scammed
Don't just trust those "live wait time" websites that look like they were designed in 2004. They often rely on historical data rather than what's actually happening on the ground.
The most reliable way is the MyTSA app. It uses crowdsourced data and reported figures from the sensors in the ceiling. It’s surprisingly accurate for MDW. Another pro tip? Check the FlyChicago website. They have a live feed for both O'Hare and Midway.
Also, honestly, just look at Twitter (X). Search "Midway security" and sort by "Latest." If there’s a disaster happening, Chicagoans will be the first to post a photo of the line stretching to the parking garage. It’s the most honest "sensor" we have.
The "Backdoor" Mentality
Some people think they can game the system by arriving at a specific minute. There's a rumor that "mid-day is always empty." That’s a gamble. While 11:00 AM is generally quieter, all it takes is one delayed flight from the morning to push a crowd into that window.
One thing that does work: if the main security entrance looks like a mosh pit, check the signage for any redirected lanes. Occasionally, they will open an auxiliary lane for families or those with disabilities that can take some pressure off the main line, though this is rare at MDW compared to larger hubs.

Beyond the Metal Detector
Once you’re through, you aren’t home free. Midway’s terminal layout is a "T" shape. Concourse A is a hike. If your flight is at the far end of A (like Gate A15), you need to factor in a solid 7 to 10-minute walk after security.
People miss flights at Midway because they get through security with 15 minutes to spare, think they have time for a coffee, and then realize their gate is a quarter-mile away.
Making Your Trip Through MDW Painless
The goal isn't just to survive the line; it's to beat it. If you want to handle Midway airport security wait times like a local, you need a plan that doesn't rely on luck. Luck is for people who end up sprinting through the terminal sweating through their business casual.
Actionable Steps for Your Next MDW Departure:
- Check the "Bridge" status before you park. If you see the line through the glass windows as you’re walking from the CTA or the garage, you know you’re in for a 30-minute wait. Adjust your pace. Don't stop for a snack before security.
- Download the MyTSA App. Use the "Plan for crowds" feature to see what the typical volume looks like for your specific flight time. It’s better than guessing.
- Pack your electronics strategically. Midway’s TSA can be "moody." Sometimes they want tablets out; sometimes they don't. Have them in an outside pocket so you aren't digging through your laundry while a businessman behind you sighs loudly.
- Enroll in PreCheck if you haven't. Seriously. Even if you only fly twice a year, the time saved at Midway alone justifies the cost.
- Monitor the Southwest app. If your flight is delayed, don't rush. But if the flight before yours is canceled, expect the security line to get weirdly quiet and then suddenly surge as rebooked passengers arrive.
The reality of Midway is that it’s a high-volume, single-point-of-failure airport. It works beautifully until it doesn't. By understanding that the bridge is your primary indicator of trouble and knowing the peak surge times, you can navigate the security gauntlet without the heart palpitations. Just remember: at MDW, the line is the destination until you're finally standing in front of that X-ray machine. Give yourself the buffer, get through the checkpoint, and then enjoy your Chicago hot dog in Concourse B in peace.
