Overview

ATL is the IATA airport code stored in this dataset for Hartsfield-Jackson Atlanta International Airport in Atlanta, United States (US). The matching ICAO identifier is KATL. Travel agents see ATL on tickets, baggage tags, and GDS segment city pairs (six letters, for example ATLLHR when the other airport is London Heathrow). ICAO KATL 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 ATL 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: ATL. To turn a booked PNR that contains ATL into a customer itinerary, paste the cryptic text into the PNR parser.
