The purpose of Accreditation is to formally recognise travel agents that are authorised to sell and issue international airline tickets.

Various responsibilities are involved. Primarily, Accredited agents are accepting payments from customers on behalf of the airlines whose tickets are issued. It is essential that customers and airlines can rely on those agents for tickets to be issued according to the required standards, and for payments to reach the airlines in a timely manner.
The Accreditation process has a set of criteria that need to be achieved. They are global in nature, but may be adapted to meet local requirements.
