Travel & Tourism Providers (TIESS Suppliers) Support Contact

Car Rentals, Hotels, Tour Operators, Rail, Cruise Lines, Global Distribution Systems, Bus Companies, Theme and Amusement Parks, among others, are Travel and Tourism Industry's Providers. For TIESS, they are or can be TIESS Suppliers.

IATA has been processing Airline's transactions and managing settlement processes with the Travel Agencies for more than 40 years through programs like the BSP (Business and Settlement Plan) and CASS (Cargo Account Settlement Solutions). During all those years, non-airline industry suppliers have always requested an IATA solution to execute a similar service on their market segments. TIESS is the IATA answer to that request.
