MDW Airport Code: Chicago Airport IATA & ICAO

Chicago Midway International Airport (MDW) is stored for Chicago, United States. ICAO KMDW. Timezone America/Chicago. This page does not list live flights, fares or terminals.

Overview

MDW is the IATA airport code stored in this dataset for Chicago Midway International Airport in Chicago, United States (US). The matching ICAO identifier is KMDW. Travel agents see MDW on tickets, baggage tags, and GDS segment city pairs (six letters, for example MDWLHR when the other airport is London Heathrow). ICAO KMDW is used in flight plans and ATC, not as the two-or-three-character GDS city-pair token. The IANA timezone recorded for local GDS times at this airport is America/Chicago. This code page explains how MDW is used in PNR text. It is not a live departures board. Terminal maps, contact phone numbers, lounge lists, and published flight schedules are not available in this dataset and are not invented here. Nearby airports stored for United States: JFK (New York), EWR (Newark), LGA (New York), LAX (Los Angeles), SFO (San Francisco). Related IATA city code in this dataset: CHI. To turn a booked PNR that contains MDW into a customer itinerary, paste the cryptic text into the PNR parser.

Example

Example GDS segment using this airport as origin: 2 AI 101 J 12OCT 1 MDWLHR HK1 0945 1510 12OCT E The parser should read MDW as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If MDW is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
