IATA is an international trade association which represents over 240 airlines, including the majority of the world’s major carriers, including British Airways, Virgin and Emirates. Based in Montreal, Canada, with executive offices in Geneva, Switzerland, IATA’s primary role is to help formulate industry policy and standards, while offering support services to all airline activity. The 3-letter airport code on your AirCharter’ flight confirmation is the IATA identification code, the same as you see on your luggage when traveling commercial.
