Passengers at two Scottish airports experienced delays over the weekend due to issues with jet fuel supply.
Those travelling through Glasgow and Edinburgh airports on Sunday faced delays on a number of flights which had to make extra stops for fuel.
It is understood the issue was due to short term staffing issues and it has now been resolved due to overnight deliveries.
The fuel issue was not related to any wider to wider geopolitical events. Both Edinburgh and Glasgow airports said the airports remained fully operational.
A spokesperson for Glasgow Airport said there was no widespread disruption to operations, and despite some delays flights were getting to their destinations.
They said: "A short‑term staffing issue has affected one of the fuel suppliers used by airlines at the airport, with work underway to return stock levels to normal.
"There have been no related flight cancellations."
It is understood airlines are responsible for sourcing and buying their own fuel, while airports provide storage and infrastructure.
A spokesperson for Edinburgh Airport also confirmed the issue has been resolved with minimum disruption.
He said: "Deliveries are now arriving and the airport is running as normal."
British Airways was among airlines affected by the problem.
A spokesperson said BA flights from Edinburgh and Glasgow were operating and they were not significantly affected.
