Understanding airport names and IATA codes
Learn why three-letter airport codes matter when searching for flights worldwide.
Guide
IATA airport codes are short identifiers used by travel systems to distinguish airports. For example, DEL identifies Delhi's Indira Gandhi International Airport and DXB identifies Dubai International Airport.
Large metropolitan areas can have more than one airport. Selecting the exact airport from an autocomplete list helps prevent mistakes caused by typing only a city name.
After choosing an airport, verify the displayed city and country. On a multi-airport trip, also check the transfer time between airports if your itinerary requires changing locations.
Frequently asked questions
Why does the airport code matter?
It helps the search system identify the exact airport rather than a broad city or region.
Can a city have multiple airports?
Yes. Major cities may have multiple airports, so always confirm the airport name and code before booking.
Before you travel
