FAQ
Frequently Asked Questions
Often, but not always. Major cities with one main airport often share the code (e.g., PAR for Paris-Charles de Gaulle). However, cities with multiple airports have different codes (e.g., LHR, LGW, STN for London). Some codes are derived from historical airport names.
The three-letter codes are assigned by the International Air Transport Association (IATA). The four-letter codes used for flight operations are assigned by the International Civil Aviation Organization (ICAO).
Very rarely. Codes are generally retired when an airport closes and are reassigned only after a significant period, if at all, to avoid confusion in historical records and systems.
Codes are often based on the airport's original or historical name (ORD for Chicago O'Hare, from its former name Orchard Field), or due to conflicts where the logical code was already taken by another airport.
