The U.K. will allow international travel to limited destinations from May 17 as it looks to allow people to enjoy quarantine-free holidays.

Portugal, Israel, New Zealand, Australia and Singapore made it into the list of countries green-listed for travel, with the list set to be reviewed every three weeks.

The latest development announced on Friday by transport minister Grant Shapps left out other popular holiday destinations such as Greece, France and Spain. The United States was also left out.

Travelers to these countries will be required to self-isolate upon returning to the U.K.

The latest advisory on international travel, despite allowing only a limited number of countries on the green list, is a welcome move for the aviation sector which has been battered by the pandemic effects.

The U.K. has prohibited non-essential foreign travel since early January. Leaving air travel companies reeling in losses.

The sector hopes more Britons will travel abroad for the holidays.
