Volcanic ash affects Cornwall to Scotland flights
Some flights between Cornwall and Scotland have been cancelled because of drifting ash from the Grimsvotn volcano eruption in Iceland.
On Tuesday, Newquay Airport said its Air Southwest service to Aberdeen and Glasgow had been cancelled.
The airport has asked passengers to contact their airlines for information.
Scientists said the ash cloud was not expected to cause the kind of disruption seen when Eyjafjallajokull erupted in April 2010.
Ash is due to reach more of the UK later in the week, when it could cause problems with flights to places other than Scotland, the airport said.
They said the material produced this time was likely to be in the form of larger grains that would fall out of the atmosphere much faster.
