The International Air Transport Association divides the world into three areas called the Traffic Conference Areas for air travel purposes. These areas are used to define geographical boundaries for fare construction and other industry-related practices:

Traffic Conference Area 1 – this area includes the Americas, encompassing North America and South America.
Traffic Conference Area 2 – this area includes the EMEA region, encompassing Europe, the Middle East, and Africa.
Traffic Conference Area 3 – this area includes the Asia–Pacific region, encompassing the rest of Asia and Oceania.

Essentially, TC1 covers the "New World", while TC2 and TC3 together cover the "Old World" and the "Land Down Under".
