Aberdeen Airport was faced with another night of travel misery tonight, as 17 flights were cancelled or diverted due to heavy fog.
Six departures – including flights to Birmingham Gatwick, and Manchester – were cancelled from about 6pm.
A 5.25am flight to Frankfurt which was due to leave later tomorrow morning was also cancelled.
Six flights which were headed to the city were also grounded.
Meanwhile, five flights were diverted away from the Granite City, with three landing in Inverness.
Passengers travelling from Gdansk, Poland landed in Edinburgh and were forced to travel home on coaches, while the crew flew the plane back to allow a return flight to depart.
Flights to Manchester, Birmingham and London City were also expected to be scrapped this morning.
Last night airport officals said while there had been two days of disruption, they were hopeful it would be “business as usual” later today.
A spokesman for the airport said: “Obviously it’s all dependent on the weather, but the fog warning we have got is only in place till 5am so hopefully it will be back to normal later in the morning.”
Inverness Airport offered temporary sanctuary to a record number of aircraft diverted while en route to or from fogbound Aberdeen.
In all, 13 helicopters and eight planes including easyJet aircraft headed for the safety of the Highland capital.
They flanked the Inverness runway overnight and much of yesterday wed as the various crews awaited clearer skies.
Callum Smith, duty manager at Inverness Airport, said: “Obviously, when fog comes in the landing criteria changes. The helicopter crews always have a divert airport in mind and we were delighted that we were able to support them and help them.”
He said it was a relatively rare occurrence for such large numbers of aircraft would to require the assistance.
Yesterday afternoon, Aberdeen airport confirmed it was forced to cancel 10 flights heading to and from the city as a “knock-on” effect from Tuesday night’s fog.
Flights to locations including Humberside, London City and Scatsta were all affected.
Inglis Lyon, managing director of Highlands and Islands Airports Ltd, praised the efficiency of the operation.
“The boys have done so well getting them all in, they were brilliant.”
Almost 70 flights were ultimately cancelled or diverted because of the fog which had drifted in from the North Sea across both days.
