Security procedures at the Duluth International Airport are very similar to those at other airports. Every passenger has to pass through the control procedures that are operated and controlled by the Transportation Security Administration. Because of this, it is always better for travelers to plan in advance in case of having connecting flights.
The arrival security procedures include body scanner and proper checking of passenger’s baggage. Everyone must cooperate with TSA agents in order for the procedures to go smoothly, without inconveniences.
Customs and Border Protection
Since the airport is international, it has the in-house U.S. Customs operated as required. CBP agents are responsible for keeping the border safe. Passengers should cooperate with the representatives by answering all the questions honestly and truthfully. The questions mostly are about the purpose of the traveler's visit and other details.
