The GTMC has announced that Virgin Atlantic and joint venture partner Delta have become its latest industry partner.
The agreement means the two airlines join others including British Airways, American Airlines, Easyjet and Etihad in the organisation.
GTMC CEO Paul Wait said: “We are thrilled to have the Virgin Atlantic/Delta joint venture join as industry partners.
“It is a critical time for airlines and TMCs in the business travel sector with some airlines not valuing the crucial role that TMCs perform in the selling, servicing and distribution of airlines’ products and services.”
He added: “Those airline partners within the GTMC, the voice of business travel, are making a clear statement and commitment in support of the GTMC members and third party distribution.”
The Virgin Atlantic and Delta partnership launched in January 2014, created a trans-Atlantic route network that offers customers up to 39 flights a day from the UK to 15 nonstop destinations in the United States.
