The IATA/IATAN ID Card is part of a global program that identifies working personnel associated with all IATAN accredited agencies. It also is relied upon by suppliers as a convenient method of identifying bona fide agents who may qualify for reduced rate travel or other industry concessions. Various promotions are also offered exclusively to IATA/IATAN ID Cardholders only. The computer generated list that is given to endorsed agencies is the primary, or only, record many international airlines will accept before considering granting reduced rate privileges.
