What is the IATA Tact rate?

IATA TACT Rates are rates published by The International Air Transport Association (IATA) three times a year. TACT rates are published between city pairs and can be specific to carrier and to unit load device (ULD) rate type. They are openly accessible, and are also referred to as “General Cargo Rates (GCR), “TACT Tariffs”, or “TACT Rates”. Airlines have to, for most countries, file tariffs with the relevant air transportation agency, and thse tariffs will also be used for Airwaybill rating and serve as a base for the calculation of special commodities. TACT rates can differ from the rates actually paid as these are often negotiated on a contract basis.
