Smith joined the board on 1 March after returning to the travel management company in June 2013 following four years at Thomas Cook Sport. Smith had left TMG in 2008 after eight years.
TMG chairman and chief executive officer, Ian Dunwoody, said: "I was delighted to welcome Jason back to the TMG team last summer. His enthusiasm, knowledge and contacts within the sports travel and corporate event world complement our business perfectly and have ensured that he was able to have an immediate and positive impact on our business.
"Appointing Jason to the board was the natural next step to challenge Jason to deliver the levels of growth that our business demands."
Smith added: "It is great to be back at TMG, I’m very excited about the future and pleased to have been given the responsibility to drive the company’s growth across all of our specialist trading divisions."
