Per the IATA website:
What is the difference between the IATA Accreditation and TIDS Programs? The IATA Accreditation and TIDS programs both facilitate the identification of bookings and reservations with industry suppliers such as airlines, hotels, and car rental companies.
TIDS agents however cannot issue airline tickets through IATAβs BSP (Billing and Settlement Plan), whereas IATA Accredited Agents are able to do so.
