Only one in 10 UK adults plans a trip abroad in the next six months, according to the latest YouGov research on travel intentions.
However, two out of three travellers would be willing to take a Covid test at an airport on return from travel.
The researchers did not ask whether travellers would be willing to pay for the Covid test.
The government announced the setting up of a Global Travel Taskforce last week which will make recommendations on a Covid testing regime at borders to be paid for by travellers.
The tests could cost £150 a time, with a negative test after several days of self-isolation allowing an early end to quarantine.
A reluctance to travel internationally for the next six months would extend to the end of March, with the Easter 2021 weekend falling on April 2-5.
The YouGov study, conducted at the end of September, also found a drop of 12 percentage points to 34% in the proportion of UK adults planning a domestic holiday in the next six months.
However, that decline would fit the normal seasonal pattern.
Surprisingly, the research found one third (32%) of adults said they would be willing to travel and self-isolate for two weeks on their return to the UK in line with government quarantine restrictions.
Younger travellers aged 18-24 and those aged over 65 were most happy to self-isolate, with 35% of both groups saying they would do so.
YouGov found better off young adults in London were most likely to have international travel plans, with 19% of Londoners planning to travel, along with 16% of 18-24-year-olds and 14% of those in social class ABC1.
The YouGov survey was conducted on September 28-29.
