Dundee Airport will be closed on Tuesday because of a strike by air traffic controllers.
Strikes were called after controllers rejected the latest pay offer made by HIAL, the company which runs Dundee Airport.
The industrial action will hit six airports over three days.
HIAL managing director Inglis Lyon apologised for the disruption and urged Prospect, the union representing the air traffic controllers, to get back round the negotiating table.
He said: “We deeply regret the inconvenience and upset to hundreds of passengers affected by the strike action.
“We wish to find a resolution to this dispute as soon as possible and would urge Prospect to sit down with us once again to find some common ground on which we can arrive at a negotiated settlement.”
Inverness Airport will be closed tomorrow with Sumburgh and Kirkwall Airports shut on Tuesday.
Dundee, Stornoway and Benbecula airports will all be closed on Tuesday.
