New Iceland Volcanic Ash Cloud Flight Restrictions – See Satellite image of dust coverate
Many UK airports are closed until at least 0100 BST on Monday because of volcanic ash from Iceland, with more disruption likely over coming days.
A Met Office forecaster said ash which exceeded the acceptable level for flights would "clip" London in the early hours of Monday morning, but the plume would drift away during Monday night and Tuesday.
Manchester, Liverpool, East Midlands, Birmingham, Teesside, Norwich and Doncaster airports are among those closed in England.
Airports in Northern Ireland, Prestwick near Glasgow, some Scottish islands and the Isle of Man are also affected.
London airports are open. Travellers are urged to check with their airline.
The air traffic authority Nats said the Civil Aviation Authority had been forced to extend a no-fly zone imposed earlier on Sunday after the ash cloud had spread further south.
In England, other airports inside the no-fly zone include Humberside, Leeds Bradford, Blackpool, Sheffield, Doncaster and Carlisle.
In Wales, Caernarfon is the only airport affected.
All three Northern Ireland airports - Belfast International, George Best Belfast City Airport and City of Derry Airport - have also been shut.
