“We’re looking forward to sharing knowledge and best practice within the Advantage Business Travel network”.

Advantage Travel Partnership chief executive Julia Lo Bue-Said added: ‘‘Diversity Travel’s continued work in support of charity and academic services is incredibly inspiring and we look forward to assisting them in growing their business and network of academic clients through a wide range of added value products and services available at Advantage and WIN Global Travel Network.”
