The Wayne County Airport Authority was established in 2002 by the Michigan State Legislature as an independent agency responsible for the operation of Detroit Metropolitan Wayne County Airport (DTW) and Willow Run Airport (YIP). Having welcomed more than 34 million passengers in 2018, Detroit Metro Airport (DTW) is Michigan's busiest airport and one of the world's leading air transportation hubs. DTW offers more than 1000 daily flights with 13 airlines to and from 120+ destinations on three continents. With two state-of-the-art passenger terminals, six jet runways, and an onsite AAA Four-Diamond Westin hotel, DTW is among the world's most efficient, customer friendly and operationally capable airports in North America. In 2020, DTW earned Airports Council International's (ACI) Airport Service Quality (ASQ) Award for Best Airport by Size and Region (25 to 40 million passengers per year in North America).Willow Run Airport, which once housed the world's busiest aircraft bomber plant to produce the B-24 Liberator for World War II, today remains an important part of the Southeast Michigan air transportation infrastructure as a reliever to DTW serving air cargo, general and corporate aviation.The Airport Authority is entirely self-sustaining and does not receive any tax dollars to support airport operations.
