Detroit (DTW) Security Tips

DTW has 3 security checkpoints with TSA PreCheck lanes and CLEAR biometric lanes. Security is busiest 5:30–8:30 AM and 3–6:30 PM. Use the Leave-By Time calculator to fold the live DTW checkpoint wait, your drive, and gate-walk into one exact departure time.

How many security checkpoints does DTW have?

DTW has 3 security checkpoints across 2 terminals (McNamara, North). TSA PreCheck dedicated lanes are available, giving members a faster, bin-free screening experience. PreCheck is open at the main checkpoints during regular screening hours, though an individual lane can close off-peak. CLEAR biometric kiosks are also deployed at DTW, letting enrolled members skip the ID-verification queue entirely. See CLEAR at DTW for details.

When is DTW security busiest?

DTW security lines are typically longest during 5:30–8:30 AM and 3–6:30 PM. Outside those windows, wait times drop substantially — check the live DTW wait board for the current picture before you head out. General guidance:

• Domestic flights: arrive at least 2 hours before departure; 2.5 hours during peak periods.
• International flights: arrive at least 3 hours before departure to cover check-in, security, and any customs pre-clearance.

Not sure when to leave? The Leave-By Time calculator uses the live DTW checkpoint wait, real-time traffic, and your gate-walk distance to give you an exact departure time. Also see how early to arrive at the airport for a full breakdown by flight type.

Which DTW security checkpoint is fastest?

McNamara Terminal North checkpoint (Concourses A/B) is usually faster than the South checkpoint; North Terminal checkpoint is consistently quick.

CLEAR is available at DTW and can be stacked with TSA PreCheck for the fastest path through security: CLEAR handles the biometric ID verification, PreCheck handles the bin-free lane. If you frequently travel through DTW during peak windows, combining both programs is the most effective approach. See CLEAR at DTW for kiosk locations and current status.

What are the top DTW airport security tips?

These tips are specific to Detroit (DTW) and verified against current airport configuration:

• DTW has two terminals: McNamara (T1, Delta hub with Concourses A, B, C) and North Terminal (T2, smaller with one concourse); each has its own checkpoint.
• McNamara Terminal is one of the longest single-terminal concourses in the US at nearly a mile — allow 10–15 minutes to reach far B or C gates after clearing security.
• The McNamara concourse tram connects the central hub to satellite Concourse A South; take the tram for far gates to avoid the full walking distance.
• Delta's hub traffic peaks Monday mornings and Thursday/Friday afternoons; PreCheck and CLEAR are both available and reduce wait times substantially during these windows.
• North Terminal is smaller, nearly always fast, and serves a handful of domestic and international carriers; an excellent low-stress security experience if your flight departs from there.

Does DTW have TSA PreCheck?

Yes — DTW has TSA PreCheck lanes at its security checkpoints. PreCheck members keep shoes, belts, light jackets, laptops, and 3-1-1 liquids packed, and pass through a dedicated screening lane. Membership costs $85–$100 for five years and includes a Known Traveler Number (KTN) you add to every booking.

See live PreCheck wait times and current lane status on the DTW TSA PreCheck page. That page also covers which terminals have a PreCheck lane, enrollment locations, and how PreCheck compares to CLEAR and Global Entry at DTW.

Global Entry interviews can be completed at DTW itself — via an on-site enrollment center or Enrollment on Arrival after an international flight — and membership includes TSA PreCheck. See Global Entry at DTW for locations and hours.
