Security wait times at DTW can vary, but with the right strategies, you can reduce the stress of long lines. For a smoother experience, aim to arrive early—2 hours for domestic flights and 3 hours for international. TSA PreCheck is a great option to avoid the regular security lines and expedite the process. Be sure to check the real-time security wait time updates on the airport’s website or app for the most accurate information. Additionally, flying during less busy hours, such as early mornings, often results in shorter wait times, allowing for a more relaxed start to your journey.
