Detroit Airport Security Wait Times & DTW Queue Guide 2026

Detroit Airport Security Wait Times Today

The Detroit Airport security wait time estimates below show the typical DTW queue at each terminal checkpoint for this hour and day of week. Detroit Metropolitan Wayne County Airport (DTW/KDTW) is Michigan’s busiest airport and Delta Air Lines’ second-largest hub worldwide. Unlike many two-terminal airports, DTW’s McNamara and Evans Terminals sit on opposite sides of the airfield with no airside connection between them. Your security checkpoint depends entirely on which terminal your airline uses, and the wait time experience at each is quite different. The McNamara Terminal carries the majority of the airport’s traffic due to Delta’s dominant share of departures, while the Evans Terminal is a more compact single-concourse facility serving all other carriers.

How Long Is Security at Detroit Airport?

Security wait times at Detroit Metropolitan Wayne County Airport are generally more manageable than at larger US hubs, but the gap between peak and off-peak is still significant. During quiet midweek windows from 10:00 to 15:00, most passengers clear a checkpoint in 10 to 15 minutes in the standard lane at either terminal. During the morning peak from 07:00 to 09:00, waits of 25 to 40 minutes are common in the standard lane at the McNamara Terminal, driven by Delta’s morning hub departure banks that push large volumes of passengers through the Level 3 checkpoint in a short window. The afternoon peak from 16:00 to 18:00 is the second daily pressure point. Peak summer travel months of July and August can push both terminals above their typical ranges.

TSA PreCheck members at DTW typically clear the dedicated PreCheck lane in under 10 minutes at most hours. CLEAR members who also hold PreCheck achieve the fastest overall experience: CLEAR handles the identity verification step biometrically at a kiosk, sending you directly past the document check queue to the physical screening area, and PreCheck handles the screening itself with no shoe or laptop removal required. The TSA PreCheck enrollment center is located at the McNamara Terminal near the domestic baggage claim area, making it convenient to apply even during a travel day if time permits.

Concourse A in the McNamara Terminal is nearly one mile long and is the second-longest airport concourse in the world. Even after clearing security, passengers heading to gates at the far end of Concourse A need to factor the ExpressTram into their pre-flight time. The ExpressTram is a free automated shuttle that runs within Concourse A and significantly cuts the walking time to distant gates. Passengers heading to Concourses B and C access them via the underground LED light-and-sound tunnel from the far end of Concourse A. Factor this internal transit time into your total airport arrival window regardless of how quickly you clear security.

Detroit Airport Security History and Improvements

Detroit Metropolitan Wayne County Airport’s security operation has been shaped by the asymmetric traffic split between its two terminals. The McNamara Terminal, opened in 2002 at a cost of $1.2 billion, was purpose-built as a Delta hub facility with security throughput in mind. Its Level 3 checkpoint is the main access point for the majority of DTW’s daily passengers, handling the volume of Delta’s hub connections, leisure traffic and the airport’s growing international route network. The Evans Terminal checkpoint, serving the smaller single Concourse D, operates at a lower volume and typically carries shorter queues.

CT scanner technology was rolled out at DTW security checkpoints starting in 2023, replacing older X-ray systems. The technology is now active at all checkpoints across both terminals. CT scanners create a 3D image of bag contents and allow passengers to leave laptops in their carry-on bag rather than removing them for separate bin screening. At CT-equipped lanes at DTW, passengers can also leave 3-1-1 compliant liquids in their bag without removing them for separate tray placement. The TSA volume restriction on liquids still applies: no individual container may exceed 3.4 ounces or 100ml regardless of scanner type. CT scanners remove the need to separate these items for screening, not the quantity limit on what you can bring. TSA PreCheck members are additionally exempt from liquid separation under PreCheck program rules.

The airport also operates biometric facial recognition technology across both terminals, introduced in 2023. This system allows eligible passengers to use facial recognition at boarding gates instead of presenting a physical or digital boarding pass, speeding up the boarding process after security has been cleared. US citizens can opt out of facial recognition scans, though visiting foreign nationals are required to participate as part of the US Customs and Border Protection entry and exit program.

Detroit Airport Security Wait Times by Checkpoint

Detroit Metropolitan Wayne County Airport operates two completely separate terminals. Your security checkpoint is determined exclusively by which terminal your airline uses. The McNamara Terminal serves Delta Air Lines and its SkyTeam partners and has multiple TSA checkpoints across the terminal complex. The Evans Terminal serves all other carriers and has a single checkpoint serving the upper-level ticketing and departure area. The two terminals have no airside connection and are linked only by a free shuttle bus running approximately every 10 minutes along John Dingell Drive.

Detroit Airport Security Peak Hours and Best Times to Fly

The two busiest windows for Detroit Airport security are 07:00 to 09:00, driven by Delta’s morning hub departure banks at the McNamara Terminal combined with leisure and connecting traffic at the Evans Terminal, and 16:00 to 18:00, the afternoon peak across both terminals. Fridays and Sundays are the most congested single days at DTW. Holiday travel and summer school vacation months produce the worst conditions: peak summer months of July and August and the Thanksgiving and Christmas travel periods all generate waits well above typical daily levels across both checkpoints.

The quietest windows at Detroit Metropolitan Wayne County Airport are 10:00 to 15:00 on weekdays and after 19:00 on any day of the week. A Tuesday or Wednesday midday departure during a non-holiday, non-summer period is the most relaxed combination available at DTW in the standard lane. The early morning window from 05:00 to 07:00 is moderate relative to the 07:00 to 09:00 rush and is a reasonable option for passengers who want to avoid the main Delta hub departure wave.

Detroit Airport Priority Security Options: TSA PreCheck and CLEAR

Priority security at Detroit Metropolitan Wayne County Airport operates through the TSA program system. The two main options are TSA PreCheck and CLEAR, which can be used independently or combined for the fastest possible experience. There is no separately managed airline priority security lane at DTW beyond these TSA programs. Business class and first class ticket holders who are not enrolled in PreCheck or CLEAR queue in the standard lane regardless of ticket class.

Recommended Arrival Times at Detroit Metropolitan Wayne County Airport

The standard guidance from Detroit Metropolitan Wayne County Airport and TSA is to arrive at least 2 hours before domestic departures and 3 hours before international departures. The airport’s own website advises between 90 minutes and 2 hours for domestic flights, but the 2-hour mark is the safer target during morning and afternoon peaks and any holiday period. For passengers departing from the far end of Concourse A in the McNamara Terminal, the ExpressTram ride and any additional gate walk add meaningful time beyond clearing security. During peak holiday travel periods and summer months, add 30 to 45 minutes to both recommendations regardless of terminal.

Tips to Beat Detroit Airport Security Queues

A few practical decisions can significantly reduce your time in the DTW security queue regardless of which terminal you are using.

• Confirm your terminal before leaving home. This is the single most important step at DTW. McNamara and Evans sit on opposite sides of the airfield and have separate I-94 exits. An incorrect terminal adds 30 to 45 minutes. Check your airline’s app or boarding pass for the terminal assignment.
• Enroll in TSA PreCheck before your next DTW flight. At $78 for five years it is the most cost-effective security upgrade at Detroit Metropolitan Wayne County Airport. The on-site enrollment center in the McNamara Terminal domestic baggage claim area makes it easy to apply in person. The PreCheck lane at DTW typically clears in under 10 minutes even during the busiest morning and afternoon windows.
• Consider adding CLEAR if you fly frequently. CLEAR at $189 per year handles the identity verification step biometrically at a kiosk, removing you from the document check queue entirely. Used alongside PreCheck it produces the fastest possible experience at both DTW terminals. Frequent flyers report combined PreCheck and CLEAR wait times of 2 to 3 minutes on average at DTW.
• Use the ExpressTram in Concourse A. Concourse A is nearly one mile long. If your gate is at the far end, the ExpressTram saves 10 to 15 minutes of walking. Take it rather than walking the length of the concourse, especially during morning peaks when every minute matters.
• Check the live wait display before leaving. The official DTW homepage at metroairport.com shows real-time queue data for both terminals. If the McNamara checkpoint is showing a 35-minute wait and your flight departs in 90 minutes, leaving 20 minutes earlier is a better call than hoping the queue clears.
• Leave liquids in your bag at CT-equipped lanes. All DTW checkpoints use CT scanners, which means you do not need to remove your 3-1-1 liquid bag for separate bin placement. This removes a step from the tray-loading process and reduces the risk of a bag pull. The 3.4 ounce individual container limit still applies, so ensure your liquids comply with the volume restriction.
• Use mobile boarding passes and online check-in. Most airlines at DTW support mobile boarding passes via their apps. Delta, Southwest, United, American and Spirit all offer self-service bag drop kiosks, which shortens landside time before you reach the security queue.
• Factor in winter weather if travelling between November and March. DTW’s location in southeast Michigan means winter weather can add significant time to road journeys from downtown Detroit and the surrounding suburbs. I-94 and I-275 back up during snowstorms. Allow extra drive time when winter conditions are forecast.

Detroit Airport Layout and Terminal Overview

Detroit Metropolitan Wayne County Airport (DTW/KDTW) is Michigan’s busiest airport and Delta Air Lines’ second-largest hub worldwide. It handled 33.4 million passengers in 2025 and serves as a major connecting point for domestic and international travel across North America, Europe, Asia and the Middle East. The airport is located in Romulus, Michigan, approximately 22 miles southwest of downtown Detroit, and is accessible via I-94 and I-275. There is no direct light rail or metro connection to the airport; car, rideshare and the SMART bus route 261 are the primary surface transport options.

DTW operates two completely separate terminal buildings. The McNamara Terminal is the larger facility, serving Delta and SkyTeam partners across three concourses (A, B and C) with 121 gates. It is connected to the on-site Westin Detroit Metropolitan Airport Hotel and features the famous 700-foot underground LED light and sound tunnel linking Concourse A to Concourses B and C. The Evans Terminal (also called the North Terminal) is the smaller facility, serving all other carriers from a single Concourse D with 29 gates. Each terminal has its own parking structure: the McNamara Parking Garage connects directly to the terminal via a covered walkway, while Evans Terminal is served by the Big Blue Deck and the off-site Green Lots with shuttle service. A free shuttle bus links the two terminals roughly every 10 minutes. For the full terminal layout, concourse maps and gate assignments at DTW, see our Detroit Airport map and terminal guide.
