meaning of IATA

these are agencies accredited by the International Air Transport Association (IATA), the international regulating body for airlines, passenger sales agents and cargo agents. Having been accredited, they are trusted by the airlines to issue tickets, directly oversee the rebooking, reissuance, or revalidation of tickets issued, or cause the endorsement to other airlines in case needed.
