Since joining the business in 2018 as head of marketing, East, alongside his team, has been supporting TTNG members with their marketing needs.
Meanwhile, Garnett, who joined the business in 2016 as product and marketing executive, has advanced through more "responsible positions" within the marketing team and managed the marketing needs for the company’s homeworking division, Independent Travel Experts members.
Gary Lewis, chief executive of TTNG, said: "Within our business, we recognise and reward the hard work of our people and always look to promote internally where possible.
"Both Ross and Kristy are key members of our team who have gone above and beyond to support us throughout the pandemic, both on the operational side of the business, as well as continuing with their marketing roles.
"Our strategy is to offer our teams the platform to grow and develop and it is heart-warming to see both Kristy and Ross flourishing within our organisation."
