Flights have resumed across Britain, as the UK’s airspace is reopened.

It has been six days since planes were grounded because of safety issues from Iceland’s volcanic ash cloud moving across Europe.

British Transport Secretary Andrew Adonis says the UK’s Civil Aviation Authority has ruled airlines are now free to reschedule flights and more than 14,000 flights are expected to operate in European airspace today.

CNN’s Paula Newton says aviation authorities in Britain are raising the threshold at which they will allow planes in the air. On advice from manufacturers they believe there is a higher tolerance for the planes to go through such an ash cloud than previously thought.

More than 95,000 flights will have been canceled since the ash shutdown airspace on Thursday night.

Air New Zealand is yet to update its advisory to passengers.
