IAD Airport Code: Washington Airport IATA & ICAO

Washington Dulles International Airport (IAD) is stored for Washington, United States. ICAO KIAD. Timezone America/New_York. This page does not list live flights, fares or terminals.

Overview

IAD is the IATA airport code stored in this dataset for Washington Dulles International Airport in Washington, United States (US). The matching ICAO identifier is KIAD. Travel agents see IAD on tickets, baggage tags, and GDS segment city pairs (six letters, for example IADLHR when the other airport is London Heathrow). ICAO KIAD 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/New_York. This code page explains how IAD 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: WAS. To turn a booked PNR that contains IAD into a customer itinerary, paste the cryptic text into the PNR parser.

How to use this page

Confirm the three-letter token on the ticket or PNR is IAD, not a similar code.

Convert and check that city and timezone match this record.
Use the airport-code page if you only need IATA versus ICAO for IAD.
Do not copy terminal or lounge claims from other websites onto this page. They are not stored here.

Example

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