How Long Are TSA Lines at Midway Airport: Peak vs Quiet Times
TSA wait times at Midway Airport run 10 to 20 minutes during peak hours and under 5 minutes when it’s quiet, so the time of day decides everything about how long tsa lines at midway airport will be before a trip.
Your airline, whether you hold TSA PreCheck, and which checkpoint you walk toward all change that number. The rest of this page shows you exactly how to read those conditions for your own flight.
Who needs Midway TSA wait times
Three kinds of travelers look up Midway security lines, and they don’t need the same thing. A business flyer with a tight connection wants the fastest route through the terminal right now. A family flying Southwest for the first time needs to know when to leave the hotel so they aren’t running through the concourse. A local who flies once a year just wants a safe arrival buffer that won’t waste their morning.
This page serves the occasional traveler heading out on a standard domestic flight without PreCheck. It assumes you’re flying from one of Midway’s main concourses during normal operating hours. If you hold Global Entry or CLEAR, your actual wait will be shorter than what’s described here, and you should check your program’s specific lane guidance instead.

What changes your wait time
The hour you arrive at the terminal moves your wait more than anything else. Midway handles heavy traffic between 5:00 AM and 8:00 AM, then again around midday. Show up at 9:30 AM on a Tuesday and you’ll walk straight through; hit the 6:00 AM rush and you’ll stand in line for twenty minutes.
Southwest Airlines operates most of Midway’s flights, and their boarding schedule creates sudden crowds. When three Southwest flights board within the same thirty-minute window, the main checkpoint fills up fast. Check your flight’s scheduled departure and count backward to see if you overlap with a busy wave.
Having TSA PreCheck cuts your physical wait down to roughly five minutes even when the standard lanes back up. You can check your boarding pass to see if the PreCheck indicator is printed there before you leave for the airport.
The checkpoint you choose matters too. Midway opens different lanes based on passenger volume. Walking into a secondary checkpoint when the main one is packed can save you ten minutes, but only if your gate is nearby. The variable here is your specific flight’s departure time, and you can read your own current estimate off the TSA wait time tool before leaving home.
How to get through Midway security fast
You don’t control how many people fly today, but you control when you walk through the doors. Follow these steps to keep your wait as short as possible.
- Check the TSA website or app for Midway’s current wait estimate two hours before you leave your house.
- Arrive at the terminal 90 minutes before a domestic flight during off-peak hours, or a full 2 hours if your flight leaves between 5:00 AM and 8:00 AM.
- Look at the overhead signs near the entrance to find which checkpoints are currently open.
- Pick the lane with the fewest people carrying large bags, since families with strollers slow down the belt.
- Have your ID and boarding pass in your hand before you reach the front of the queue.
- Put your liquids bag and electronics in the bins immediately when you reach the conveyor belt.
- Step through the scanner as soon as the officer waves you forward, without waiting for the person ahead to clear completely.
- Grab your bins and move to the benches past the checkpoint to put your shoes back on.
The single judgment call that separates a smooth exit from a stressful one happens at step four. Don’t just pick the shortest line; pick the one moving fastest. A short line full of travelers untying boots and digging through backpacks takes longer than a slightly longer line of business travelers in slip-on shoes. If the line stops moving for more than two minutes, ask an officer if another lane is opening rather than standing still.
Wait times by travel situation
Different trips demand different buffers at the security line. Here’s how the main scenarios break down so you can plan your arrival.
| Your situation | What to do | Time needed | Watch out for |
|---|---|---|---|
| Early morning flight | Arrive very early | 2 hours | Staff shift changes |
| Midday weekday trip | Standard arrival works | 90 minutes | School groups |
| Holiday weekend travel | Add extra buffer | 2.5 hours | Fully packed bins |
| Flying with TSA PreCheck | Use dedicated lane | 45 minutes | Expired membership status |
| Connecting through Midway | Follow re-entry signs | 60 minutes | Terminal changes required |
| Late night departure | Checkpoint closes early | 90 minutes | Reduced open lanes |
Getting Midway security right
Reading the crowd before you join it
Stand near the entrance for ten seconds before picking a lane. Watch how fast the belts are turning. If officers are pulling people aside for bag checks in every lane, add ten minutes to whatever estimate you saw online. Travelers who skip this pause end up stuck behind someone whose bag gets flagged, losing fifteen minutes they didn’t budget for.
Packing for the scanner, not the plane
Put your laptop and liquids bag at the very top of your carry-on before you leave home. At the checkpoint, you shouldn’t have to dig past clothes to find them. People who unpack their whole bag on the conveyor belt hold up everyone behind them, and officers will often pull their bin off the line entirely to clear the jam. That costs you a second screening.
Fixing Midway checkpoint problems
Things go wrong at airport security because of rushing or poor packing. Match what you see to the fix below so you don’t lose your spot in line.
| What you notice | What it usually means | What to do first | How to stop it happening again |
|---|---|---|---|
| Line stopped moving | Bag check ahead | Ask officer about other lanes | Pack liquids clearly |
| Scanner alarm sounds | Metal left in pockets | Empty pockets completely | Wear simple clothing |
| Officer pulls your bag | Prohibited item inside | Open it where directed | Check TSA rules beforehand |
| PreCheck lane closed | Staffing shortage | Join standard lane quietly | Allow extra time |
| Missed your group | Moved too slowly | Tell officer your boarding time | Keep documents ready |
Rules that govern your screening
The Transportation Security Administration sets the screening rules at Midway, and they apply to every passenger equally. You can’t bring liquids over 3.4 ounces in your carry-on, and all containers must fit inside one quart-sized bag. These limits come directly from federal regulations enforced at every US airport.
If you’re traveling with medical supplies or baby formula, TSA allows exceptions, but you must declare them to the officer before your bag hits the belt. The exact list of permitted items changes occasionally, so check the official TSA “What Can I Bring?” Page for your specific item before packing.
Don’t argue with an officer about a confiscated item at the checkpoint. If something is taken, you can either surrender it, return it to your car, or mail it to yourself using services available in the terminal. Attempting to force a prohibited item through security can result in civil penalties from the TSA.
What the wait actually costs
The real cost of a long security line isn’t money; it’s the stress of watching your boarding time tick closer while you stand still. A 20-minute wait during the morning rush costs you the chance to sit at your gate, buy coffee calmly, or use the restroom without sprinting afterward.
If you miss your flight because you underestimated the line, Southwest typically rebooks you on the next available one, but you might wait several hours for a seat. For airlines that don’t offer flat-rate standby, buying a same-day ticket at the counter costs significantly more than your original fare.
Paying for TSA PreCheck is inexpensive relative to the alternative. Divide that across two round trips a year, and it buys back roughly fifteen minutes per flight. Compare that to the price of a missed connection or a ruined morning, and the math favors the application fee for anyone flying more than twice annually.
Keeping your status active
If you applied for TSA PreCheck to shorten your Midway waits, the approval doesn’t last forever. Your Known Traveler Number expires after five years, and the system won’t warn you when your boarding pass suddenly drops the PreCheck indicator.
Set a calendar reminder six months before your expiration date. You can renew online through the TSA enrollment provider, and the process takes less time than your initial application. If your boarding pass prints without the PreCheck logo on the day of your flight, your membership has lapsed, and you’ll need to join the standard lane.
Keep your legal name updated across your frequent flyer profiles, your ID, and your PreCheck account. A mismatch between your driver’s license and your reservation is the fastest way to lose your expedited screening privileges for that trip.
When Midway isn’t the right airport
If you live north of Chicago, driving to Midway adds highway traffic that wipes out any time you save at security. O’Hare International Airport makes more sense geographically, even though its absolute wait times can be longer, because the total door-to-gate journey is shorter.
If you’re flying internationally, Midway offers very few routes. Trying to connect through it for a long-haul trip means changing airports or terminals in ways that introduce massive delays. Book your international departure from an airport with direct customs processing instead.
If you have a severe mobility issue or require specialized medical equipment that triggers constant scanner alarms, standard TSA lanes at a high-volume airport like Midway can be exhausting. Contact TSA Cares at least 72 hours before your flight to arrange assistance, or consider departing from a smaller regional airport where agents have more time to help you through screening safely.
Frequently asked questions
How early should I get to Midway Airport?
Arrive 2 hours before domestic flights during peak morning hours, or 90 minutes if you’re flying midday. This assumes you don’t have TSA PreCheck; if you do, 60 to 75 minutes is usually enough.
Does Midway Airport have TSA PreCheck lanes?
Yes, Midway has dedicated PreCheck lanes at its main security checkpoints. You’ll see signs directing you to them once you enter the screening area, provided your boarding pass shows the indicator.
Why is the Midway security line so long today?
Morning rushes between 5:00 AM and 8:00 AM cause the longest backups because multiple Southwest flights board simultaneously. Holiday weekends and staffing shortages also push wait times higher than usual.
Is it faster to use the secondary checkpoint?
It can be, especially if your gate is in Concourse B or C. However, the secondary checkpoint sometimes operates with fewer open lanes, so check the overhead monitors before walking away from the main hall.
What happens if I miss my flight due to security?
Southwest will typically rebook you on the next available flight without a change fee, though you might wait hours for an open seat. Other airlines may charge for same-day standby depending on your ticket type.
Can I check Midway wait times before leaving home?
Yes, the TSA website and app provide estimated wait times for Midway’s checkpoints. These estimates update throughout the day, but always add a 10-minute buffer for unexpected slowdowns.
Do children need TSA PreCheck to use the lane?
Children 12 and under can accompany a parent or guardian who has TSA PreCheck through the expedited lane. Teenagers 13 and older need their own PreCheck membership to use that specific line.
Does CLEAR operate at Midway Airport?
No, CLEAR kiosks aren’t currently available at Midway. You’ll rely on standard screening or TSA PreCheck to move through security faster, unlike at O’Hare where CLEAR is an option.
Your first step at Midway
Open the TSA app two hours before you leave home and check Midway’s current wait estimate. Expect to clear security within 20 minutes if you arrive during the morning rush, or under 5 minutes if you timed it for midday. If the app shows a delay exceeding 30 minutes and your flight boards soon, call your airline’s desk before you park your car.
