Chapter 3 At the end of this chapter, you will be able to: Define encoding and decoding Encode cities, airports, countries, states and airlines Make time calculations Make date calculations


Encoding and Decoding The airline industry uses a system that identifies each

city, airport, country, state or airline by a unique code– Codes are administered by the International Air Transport

Association (IATA), and the International Standards Organisation (ISO)

– With these codes, you can identify cities, airports, countries, states and airlines quicly and efficiently


Cities Note that many cities have the same name, but are located in

different countries, e.g. Paris (France, USA)


Airports Many major cities have more than one airport – e.g. New York has 8 airports– each airport has its own three-letter code

ability to encode and decode:– Airline codes and names– Airport and city codes and

Three-letter code: Cities, and airportsTwo-letter code: Countries, airlines, hotels, and rent-a-cars
