Flights have started taking off and arriving in the UK after safety tests revealed that planes are able to fly in airspace where there is low density ash.
Last night (April 20th), the Civil Aviation Authority (CAA) gave permission for services to resume at 22:00 BST after six days of disruption caused by ash from a volcanic eruption in southern Iceland.
It is the news passengers across the world had been waiting for after some 95,000 flights had had to be cancelled across Europe.
A spokesman said that airlines are working hard to clear the huge backlog of passengers that have been stranded at airports around the globe.
"It will take time for flights to settle down to normal timetables."
"If you are hoping to travel, you should check your airline’s website for up to date information about your flight in the usual before travelling to the airport," he recommended.
Virgin Atlantic is planning to operate a normal schedule today, while British Airways and easyJet flights remain disrupted.
Meanwhile, Air India has said it is planning to resume its flights to and from London from this morning.
