Portman, whose search engine product “overcomes, with one platform, the problems of compatibility, continuity and consistency”, has been recognised the GTMC.
The Travelport GTMC Awards were set up last year to recognise travel management companies (TMCs) which are “redefining travel commerce”.
Competing companies must be delivering original, innovative technology to deliver greater productivity and efficiency for customers.
PortmanOne works by pulling global airfares from multiple sources including GDS and low-cost carriers and ancillary products, before presenting a wide range of prices for the same seat.
Steve Allen, chief executive of Portman, said: “We are delighted that the innovation of PortmanOne, which we firmly believe is a game changer in the industry, was recognised by the judges.
“PortmanOne delivers high quality, comprehensive, global and local content, ensuring our clients benefit from the best fares and rates, including ancillaries such as rail and ground transport services.
“It is a cloud-based technology platform that uses metasearch principles to present content quickly and efficiently.”
Paul Wait, chief executive of the professional body the GTMC, added: “We are delighted to present our fourth award to Portman.
“PortmanOne overcomes, with one platform, the problems of compatibility, continuity and consistency faced by TMCs and their clients, which are often exacerbated by trying to bolt together several systems.
“It is a remarkable achievement.”
Simon Ferguson, managing director, UK, Ireland and the Nordics at Travelport, said: “Travelport is pleased to continue its recognition of TMCs that have taken a holistic approach to business by creating technology that saves precious time and money for both themselves and their clients.”
