DTW Security Wait Times tend to increase during peak travel seasons such as summer vacations, spring break, and major holidays. During these periods, security lines can stretch beyond 45 minutes, particularly in the early morning hours. Although TSA increases staffing during high-demand times, passenger volume often exceeds normal capacity. Travelers are strongly encouraged to arrive earlier than usual and prepare for additional screening. Packing efficiently, following TSA guidelines, and having travel documents ready can help speed up the process. Enrolling in TSA PreCheck can make a noticeable difference during peak seasons. Being proactive and allowing extra time is essential for managing DTW during busy travel periods.
