Chicago Midway International Airport

Chicago Midway International Airport (KMDW) sits 8 miles southwest of downtown Chicago. Commercial service is dominant — Southwest Airlines runs its largest base here — and the field handles a meaningful flow of business aviation, particularly close-in charter for downtown Chicago and the south-side corporate corridor where KORD's distance is impractical. The four runways at KMDW (4R/22L 6,522 ft, 13C/31C 6,446 ft, 13R/31L 5,506 ft, 4L/22R 5,141 ft) accommodate most current business jets but constrain ultra-long-range operations on hot-day departures. Atlantic Aviation and Signature operate the principal private terminals. The defining operational feature of KMDW is the short-runway environment surrounded by residential neighborhoods — Southwest's 737s land regularly but heavy bizjet operators routinely use KORD or KPWK (Chicago Executive in Wheeling) when MTOW departures are needed. Field elevation is 620 feet, no density-altitude concerns. The dominant operational considerations are winter weather (snow, freezing rain, the famous Lake Michigan effect), summer thunderstorms, and the slot pressure during peak Southwest banks. Ground time to downtown Chicago is 15–25 minutes via I-55 — meaningfully faster than KORD; the Loop and Magnificent Mile are 20–30.
