Spain’s Canary Islands have been added to the UK Government’s list of travel corridors, transport secretary Grant Shapps said.
Denmark, the Maldives and the Greek island Mykonos have also been added to the list.
Travellers arriving in Scotland from those places after 4am on Sunday no longer need to self-isolate for 14 days.
This could lead to a surge of bookings for October half-term breaks and holidaymakers seeking winter sun.
Lichtenstein is the only country to lose its quarantine exemption this week.
Andrew Flintham, managing director of Tui UK & Ireland, said the reintroduction of the Canary Islands to the travel corridor list was a “positive step” for both the business and holidaymakers seeking a winter break.
He said: “We haven’t been able to take people on a Tui holiday to the Canary Islands for 89 days, when the sudden quarantine and subsequent travel advice was imposed with little notice.
“We’re therefore delighted that UK flights will now resume from Saturday.
“The first flights will depart to Fuerteventura and Lanzarote this weekend, with many more added in the coming days.
“We urge the Government to continue to work closely with the industry on airport testing so we can open up more destinations in the coming weeks.
“We must move away, where possible, from the anxiety our industry faces waiting for the new list of places people can travel to each week.
“This level of uncertainty is damaging for business and all those employed in our industry.”
