An airport code is a short code used to identify a specific airport. There are two international systems used:
- IATA airport code, a three-letter code which is most commonly known to the public because of its use in reservation, ticketing, and baggage-handling systems
- ICAO airport code, a four-letter code which is most commonly used by air-traffic control systems and for airports that do not have an IATA airport code (generally those without scheduled commercial flights)
In the United States, Federal Aviation Administration Location Identifiers are generally the same as the IATA airport code. Small municipal or private airports that do not have an IATA airport code are given a Location Identifier that usually includes numbers (to avoid conflict with future and existing IATA airport codes).
Famous quotes containing the words airport and/or code:
“It was like taking a beloved person to the airport and returning to an empty house. I miss the people. I miss the world.”
—Susan Sontag (b. 1933)
“Faultless honesty is a sine qua non of business life. Not alone the honesty according to the moral code and the Bible. When I speak of honesty I refer to the small, hidden, evasive meannesses of our natures. I speak of the honesty of ourselves to ourselves.”
—Alice Foote MacDougall (1867–1945)
