A technical problem overnight has caused delays at all of Scotland’s main airports.
Air traffic management provider NATS said the technical fault has affected Edinburgh, Glasgow, Aberdeen and Prestwick airports.
The issues are only affecting part of Scottish airspace and flights to and from Scottish and Northern Irish airports this morning have been hit.
NATS added it has managed to “significantly reduce” the forecast delays and is now “working on bringing service levels back to normal as soon as possible”.
At Glasgow Airport three flights have been cancelled - one to Gatwick and two to Amsterdam - and delays are expected throughout the day.
There are a small number of delays on southbound flights from Aberdeen Airport.
Passengers have been advised to check the status of their flight with their airline.
