Chicago Executive Airport (PWK) is a general aviation airport just south of central Wheeling, jointly owned by the village of Wheeling and the city of Prospect Heights. It is the third-busiest airport in Illinois by movements, behind O'Hare and Midway, and is the preferred entry point for private aircraft serving the northern Chicago suburbs.
There is a public viewing area off Wolf Road where you can watch the traffic — a steady stream of business jets, training aircraft, and helicopters. The on-airport diner is open to the public and is a quiet spot for a coffee.
