Security at Duluth DLH Airport Safer. It doesn’t have to mean slower. Duluth International Airport believes that security should improve the travel experience, not impede it. So here’s what you can expect:
The 3-1-1 on air travel: 3-oz (max) containers with liquids or gels; 1 quart-size plastic zip-top bag holding 3-oz (max) containers; 1 bag per person placed in the security bin.
