Loganair has cancelled some flights in Scotland as volcanic ash from the Grimsvotn volcano in Iceland heads towards the UK.
The airline cancelled 36 flights on Tuesday and advised customers due to travel to contact them to rearrange flights. Only inter-island routes in Orkney are unaffected.
A statement from Loganair said: “We have taken the decision to cancel all services with the exception of our inter-isles flights in Orkney. All flights due to depart between 06:00 and 13:00 hrs tomorrow have therefore been cancelled.
“You should not travel to the airport and if you are booked on a flight departing tomorrow afternoon, you should check the website for further updates before setting out for the airport.
“We are operating additional services this evening (Monday 23 May) to assist passengers due to travel tomorrow to complete their journeys in advance of the expected flight disruption.”
The London-based Volcanic Ash Advisory Centre said there was a “strong possibility” that parts of the Grimsvotn volcano ash cloud may impact parts of Scotland and Ireland in the next 24 hours.
It said: “Due to unstable meteorological conditions, it is not possible to identify with certainty the movements of the ash cloud beyond that time frame.”
At the same time Eurocontrol said there had been no significant impact on flights today as a result of the eruption.
A further update is to be given tomorrow morning.
Last year’s eruption of the Eyjafjallajökull volcano crippled aviation throughout Europe, with an estimated 100,000 flights cancelled and the travel plans of around 8 million passengers disrupted.
