Detroit Metropolitan Wayne County Airport

DTW has separate security checkpoints for McNamara Terminal and Evans Terminal — there is no airside connection between the two. The McNamara Terminal has three security checkpoints: one at the south end (serving Gates A1–A28), one in the centre (serving the link to B and C concourses), and one at the north end (serving Gates A56–A78). TSA PreCheck is available at all McNamara checkpoints and at Evans Terminal. CLEAR biometric screening is available at McNamara Terminal. For Delta passengers: the Gate A38 Delta Sky Club is the most strategically located as it sits at the centre of Concourse A and is accessible from all three McNamara security checkpoints. The ExpressTram within McNamara runs frequently (every 3–4 min, free) and is the fastest way to cover the 1-mile length of Concourse A — particularly useful for passengers connecting from Gates A1–A10 to international departures at the far north end (Gates A60–A78) or vice versa. For Evans Terminal (Lufthansa, Allegiant, Breeze): the check-in and security are entirely separate — if you are connecting between terminals post-security, you CANNOT do so airside; you must exit landside and take the free inter-terminal shuttle (every 10 minutes).

International arrivals at DTW are processed at the Federal Inspection Services (CBP) facility in McNamara Terminal, accessible from Concourse A's international arrival gates (Gates A1–A30, south end). Global Entry kiosks available in the FIS facility — enrol in advance at cbp.gov to avoid potentially long CBP queues. The CBP One app (Mobile Passport Control) is also accepted for eligible passport holders. Canadian preclearance is NOT available at DTW — all Canadian arrivals clear CBP on arrival in McNamara Terminal. Detroit is a popular Canada-US crossing point due to proximity to Windsor, Ontario — expect high Canadian passenger volume and potentially longer FIS queues during summer, Thanksgiving, and Christmas periods. Connecting passengers (international arrival then domestic Delta onward) should allow minimum 60 minutes: FIS processing, baggage reclaim, recheck, and re-clearing domestic security all take time. The post-CBP baggage reclaim is at the south end of McNamara Terminal near the international arrivals exit.
