Hogg Robinson Group has signed deals with two leading GDSs Amadeus and Galileo.
The agreement with Amadeus makes the travel IT company HRG's main GDS partner in Switzerland, Austria and Lichtenstein.
Under the agreement Amadeus will provide Hogg with the latest version of its Amadeus Selling Platform.
The deal increases what Amadeus said was already a "healthy and wide-reaching collaboration between the two companies."
Albert Pozo, Amadeus' head of business travel, multinational customer group, said: "This is a very important agreement for us as it shows that our partnership approach – demonstrated across Europe with HRG - brings real value to the TMC community, so that they are willing to commit more and more business to us."
Travelport, owners of Galileo, said its deal was a long term global agreement which extends the existing contract between the two companies to include the USA for the first time.
The US is the largest GDS market in the world.
Travelport said Galileo and HRG had been working together for sometime and were currently developing new initiatives which includes the launch of HRG's Universal Super Platform.
Sandra McLeod, Travelport's vp global accounts and strategic corporate development, said: "We already have a strong and successful track record of working closely with HRG across the EMEA and Asia Pacific regions.
"Specifically, our GDS leadership in the fast-growing Asia Pacific region has particularly helped HRG to grow its business in Singapore, Hong Kong and Australia.
"We're delighted HRG has now chosen us as its global GDS partner."
