Chief executive Mark Tanzer said the association was buoyed by prospect of a 17 May restart for travel remaining on the table, subject to circumstances.

However, he said it was vital government addressed concerns over the cost of testing requirements for holidaymakers, and looked again at targeted financial support for travel.

"The travel industry now has a much-needed framework for the restart of international travel, and it is good to see government maintain its ambition for overseas travel to start from 17 May if the circumstances allow," said Tanzer.

"While the framework isn’t perfect, the requirement for a PCR test when you arrive back from a green list country could prove a cost-barrier for many people, we welcome the fact the government commits to engaging with industry on this issue."

Tanzer said "small changes", such as requiring a PCR test only if the individual gets a positive result from a lateral flow test, would make international travel more accessible and affordable "while still providing an effective mitigation against re-importation of the virus".

"The government should also consider whether those who have been vaccinated can be exempt from testing requirements, should scientific evidence suggest reduced transmissibility," said Tanzer.
