Dozens of destinations have been given the green light for travel from the UK as of today.
Travel between the UK and various long-haul destinations such as Mexico and South Africa opened up from 4am on today.
A total of 47 countries have been removed from the red list, meaning arrivals from those locations will no longer need to spend 11 nights in a quarantine hotel.
Meanwhile, the Foreign, Commonwealth and Development Office (FCDO) has lifted its advice against non-essential travel to a further 42 countries and territories due to the coronavirus pandemic.

This follows the removal of travel advisories to 41 locations last week.
The changes make it easier for people to obtain travel insurance for trips to those destinations.
They are part of a new policy to stop advising Britons to avoid all but essential travel to non-red list countries on Covid-19 grounds except in "exceptional circumstances", such as if the local healthcare system is overwhelmed.
Foreign Secretary Liz Truss has said this allows people to "exercise personal responsibility", while Transport Secretary Grant Shapps has claimed "restoring people’s confidence in travel is key to rebuilding our economy".
Countries affected by both the easing of travel advisories and the reduction in the red list include Argentina, Chile, Cuba, Indonesia, Mexico, Nepal, the Philippines, South Africa and Thailand.

Just seven countries will remain on the red list from Monday, all in Latin America.
They are Colombia, Dominican Republic, Ecuador, Haiti, Panama, Peru and Venezuela.
People arriving from those locations will still be required to enter a quarantine hotel at a cost of £2,285 for solo travellers.
Since last Monday, the government has eased the rules for travel to non-red list countries, referred to as the ‘rest of the world’ list, which replaced the amber and green categories.
People who are fully vaccinated no longer need a pre-departure test before returning from non-red list destinations, and neither do children under the age of 18 who are travelling with their vaccinated parents.
More changes are expected as later in October holidaymakers will also be able to replace the day two PCR test with a cheaper lateral flow test.
However, a formal date has been announced as to when this will come into force.
Those who test positive for coronavirus still have to isolate and take a PCR test to confirm the result.
