While the UK travel sector has been widely supportive of plans to life Covid-19 restrictions, the World Travel & Tourism Council (WTTC) has warned the process may take too long.
Prime minister, Boris Johnson, unveiled the plans on Monday, with a global travel taskforce to report on the reopening of travel on April 12th.
The government would then decide on removing restrictions on international travel.
However, this would not happen until May 17th at the earliest.
While some businesses have already reported a surge in bookings, WTTC chief executive Gloria Guevara said delays could prove costly.
She explained: “While we welcome the incredible progress the UK government has made on the vaccine rollout programme, delaying the return of international travel until at least mid-May, could mean the tourism sector simply will not survive and struggling small- and medium-sized enterprises will just disappear.
“The sector was banking its hopes on a quicker return to international travel, so there will be widespread dismay at this news.
“Its return is crucial if the UK economy is to recover from the ravages of the pandemic, given the sector generates £200 billion to the GDP of the United Kingdom and supports almost four million jobs.”
