TheInternational Air Transport Association (IATA) divides the world into three areas called the Traffic Conference Areas (TCAs) for air travel purposes. These areas are used to define geographical boundaries for fare construction and other industry-related practices:[1]
Essentially, TC1 covers the "New World", while TC2 and TC3 together cover the "Old World" (Africa-Eurasia) and the "Land Down Under".
