Changes have been made to TUI’s flight lists in the latest announcement released by the airline.
On Tuesday TUI released a list of countries they are currently operating to - along with flights which have been cancelled due to ‘ongoing uncertainty’ because of the pandemic.
A system for foreign travel came into force from Monday, with the traffic light system streamlined into just one red list of destinations which continue to pose a coronavirus risk.
Under the new rules passengers who are fully vaccinated will no longer need a pre-departure test before returning from non-red list destinations, and neither will children under the age of 18 who are travelling with their vaccinated parents.

The government has said that by the end of October holidaymakers will also be able to replace the day two PCR test with a cheaper lateral flow test - although no formal date has been announced for this yet.
Unvaccinated passengers from non-red countries will still have to test before departure and take PCR tests on day two and eight.
The government is set to announce updates to the red list later this week, following on from the last update three weeks ago.
TUI have advised customers to check the latest advice for latest Covid requirements at their destination.
