Departures from Detroit Metropolitan Wayne County Airport
The airport advises its passengers to arrive at the airport more than 90 minutes before the domestic flights and 120 minutes before the international flights.
Transportation Security Administration (TSA) provides safety during flights by making all passengers passing the security control before and after the plane as well. Thus, under the 3-1-1 regulation, TSA allows the passengers to travel with a 3.4 oz bottle, one quart-sized clear plastic bag, and one bag per passenger.
After passing the Security Control, the passengers shall proceed to the Customs & Border Protection.
When going out of the United States, right at the boarding gate, the passenger shall provide the ID card, passport, driver's license, or other TSA approved documents.
