More than three out of five people would support flights which only accept vaccinated passengers, a new survey suggests.
Some 61% of 2,105 UK adults polled by travel think tank Thrive said they would be in favour of such a move.
The boss of Australian airline Qantas has said passengers will in future need to prove they have received a coronavirus jab before they can board its international flights.
The survey indicated that 74% of people think it would be reasonable for airlines to continue insisting that passengers wear a mask, even if they have had a vaccine.
It also suggested that 79% would be happy for their vaccination details to be passed on by the NHS to a digital health app for inspection by airport officials in other countries.
Thrive senior researcher Sania Haq said: “These findings suggest consumers are now conditioned to ongoing social distancing measures which reduce transmission and prevent the spreading of Covid-19.
“It is also clear that few are worried about any privacy issues regarding their vaccination details if it means they can seamlessly access other countries and travel for business or leisure.”
The aviation industry has been badly hit by the virus crisis with demand not expected to return to 2019 levels until 2024.
