IAH Airport Code: Houston Airport IATA & ICAO

George Bush Intercontinental Airport (IAH) is stored for Houston, United States. ICAO KIAH. Timezone America/Chicago. This page does not list live flights, fares or terminals.

Overview

IAH is the IATA airport code stored in this dataset for George Bush Intercontinental Airport in Houston, United States (US). The matching ICAO identifier is KIAH. Travel agents see IAH on tickets, baggage tags, and GDS segment city pairs (six letters, for example IAHLHR when the other airport is London Heathrow). ICAO KIAH 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 IAH 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: IAH. To turn a booked PNR that contains IAH 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 IAHLHR HK1 0945 1510 12OCT E The parser should read IAH as departure. Times 0945/1510 are local as printed, not converted to your PC clock. If IAH is missing from the dataset, city and timezone enrichment stay empty rather than guessed.
