The agreement will see the two organisations collaborate on a number of projects to inspire the next generation of industry professionals.
As part of the deal, ITT Future You will host its first events in Ireland next year.
The inaugural ITT Future You "Global" event in Ireland is scheduled for autumn 2021, and follows similar events already hosted in Russia, Brazil and Kenya.
Claire Steiner, co-founder of ITT Future You, said “As ITT Future You continues to gain momentum both in the UK and internationally, we have been delighted to have supported IASA over the past few months.
"With so many of our goals aligned, it is great to be able to formalise our relationship to help support each other, in our mutual goal of promoting careers and inspiring future generations across the tourism and aviation sectors in both the UK and Ireland."
Daniel Tetis, Iasa chair, added: “Empowering the next generation is one of our main aims here at Iasa, and we are delighted to partner with ITT Future You to achieve this together.
"ITT Future You has done tremendous work in recent years giving students ideas and insights in their future careers and we believe our partnership will enable us to reach students all across Ireland and the UK and we look forward to working together on events in the future."
Speakers at ITT Future You events this year have included representatives from MSC Cruises, Party Hard Travel, Attraction World and Visit Britain.
The initiative will soon surpass 20,000 attendees having taken part in its free-to-attend events since its creation in 2008.
