FAA Great Lakes Region Region (AGL), Airports & States

About FAA Great Lakes

The Great Lakes Region administers the airports of the Midwest manufacturing belt and the Upper Midwest, anchored by Chicago O'Hare and a deep bench of medium airports that serve cross-border traffic to Canada. The FAA assigns each airport in the United States to one of nine regions; this region handles airport certification, safety inspections, federal-grant coordination, and overall coordination with the air-traffic-control facilities physically inside its territory.

For travelers, the most useful thing to know about a region is which of its airports is the closest large_airport for the trip you are planning, and which secondary or regional airports could spare you a longer drive to the major airport. The featured airports below cover the largest gateways inside the Great Lakes Region, and the state list below that gives you a way to drill into every public-use airport the region covers.
