Metro Airport, as it is popularly called, started in 1929 as Wayne County Airport when Thompson Aeronautical Corp, a predecessor of American Airlines, began passenger service from the site. It now ranks as the eighth busiest airport in North America and the 14th busiest in the world. More than 30 million passengers pass through its gates each year.
However, Metro has often ranked near the bottom in terms of passenger service and when it comes to issues such as luggage handling and the ability to handle the growing number of passengers which continue to flow through its terminals. The Midfield Terminal project is designed to bring Metro into the 21st century as a state-of-the-art transportation center.
