This document provides information about MD. Shaifullar Rabbi's professional experience and qualifications, as well as an overview of IATA's geography and traffic conference areas. IATA has divided the world into three traffic conference areas (TC1, TC2, TC3) for standardizing fares. TC1 includes North America, Central America, the Caribbean, and South America. TC2 includes Europe, Africa, and parts of Asia west of Iran. TC3 includes the rest of Asia, Australia, New Zealand, and the Pacific islands. IATA geography is important for airlines to understand countries, destinations, climates, and properly plan and price air travel.
