Rajeev Shaunak, head of travel and tourism for MHA, said a large proportion of the sector "remains on life support" due to the Covid-19 pandemic.
"The chancellor’s autumn budget statement must offer the UK’s travel sector hope for, not fear of, the future," Shaunak said.
"The industry remains in critical need of support to come through the strife of the Covid-19 pandemic and Rishi Sunak needs to win it over and deliver, especially as additional factors such as growing inflation, increasing national insurance contributions, labour shortages and a potential energy crisis could place even greater strain on businesses."
