Aviation terms, airport and airline codes, automotive features, driving and licensing, rail, transit and maritime abbreviations. Codes such as LAX or DFW are assigned by IATA and appear on every boarding pass and baggage tag.
Airport Code Abbreviations
Three-letter IATA airport codes for the busiest and most-searched airports in the United States, Canada, Latin America, Europe, Asia, Africa and Oceania. IATA codes appear on tickets, boarding passes, baggage tags and departure boards, while pilots and air traffic controllers use separate four-letter ICAO codes, which are noted on each page. Many codes are obvious abbreviations of the city name, but others preserve the names of old airfields, military bases or radio stations.

Two-character IATA airline designators for major passenger airlines in North America, Europe, the Middle East, Asia, Oceania, Latin America and Africa.
