The Prairie State with Chicago as a global hub of industry and culture.
Fun fact: Chicago O'Hare is one of the busiest airports in the world!
Chicago O'Hare and Midway anchor one of the world's densest airline markets, while Chicago Executive (KPWK) and DuPage (KDPA) sustain a strong corporate-GA base and affordable downstate fields like Springfield keep training busy.
Best season: May–June and September–October are best; winter lake-effect clouds and summer convective lines rolling off the plains are the hazards.
Airspace: O'Hare (KORD) and Midway Class B plus crowded Class D relievers make metro-Chicago VFR challenging; the Lake Michigan shoreline corridor and heavy arrival flows require precision.
