It comes after the Advantage Travel Partnership took a majority share in WIN in 2017 after a long association with the network, which comprises a wide-ranging roster of international corporate travel experts.
Partners now span more than 6,000 locations across 81 countries.
Advantage said the rebrand had been prompted by the "increased brand awareness and recognition Advantage has achieved in recent years and especially during the pandemic".
It also said the move would align and simplify the group’s business travel proposition. The rebrand was announced at the Business Travel Show on Thursday (30 September).
The network is an exclusive benefit to Advantage members, who can call on partners to provide in-country, on the ground support and knowledge.
Advantage chief executive Julia Lo Bue-Said said: “Bringing consistency of name will strengthen our global business travel offering and better incorporate the global network into our core business, making it easier for UK members and international partners to communicate its benefits and facilitate collaborative enterprises with each other."
