Search by the three-letter code, the city, or the airport name, major world airports, instantly.
IATA codes are the three-letter identifiers on tickets, boarding passes and luggage tags, assigned to airports worldwide. Some are obvious (MIA for Miami), some come from earlier names (ORD from Orchard Field, Chicago), and some follow the city rather than the airport (NYC-area travellers meet JFK, LGA and EWR). This lookup covers the major international and large domestic airports, the ones that appear on the overwhelming majority of itineraries, with the city, country and the airport's local UTC offset zone name.
Smaller regional fields are not included; for an airfield absent here, the code printed on the ticket plus a map search is the reliable route. Codes are also occasionally shared with railway stations in IATA's system, another reason this table sticks to airports proper.
Why is Chicago ORD and not CHI? ORD survives from the airport's original name, Orchard Field. CHI is the city code covering all Chicago airports, both systems coexist.
Is the code on my luggage tag the destination? Yes, the tag shows the destination airport's IATA code (and connections in order), which is why handlers worldwide can sort bags without a shared language.
Are time zones the current offset? The table lists the zone name (for example America/Chicago) rather than a fixed offset, because the numeric offset changes with daylight saving.
