Six Scottish regional airports have been closed due to a one-day strike by air traffic controllers.
The Prospect union members are in a dispute with employer Highlands and Islands Airports Ltd (Hial) over plans to centralise some air traffic control.
Scottish government-owned Hial says it must modernise the service.
Benbecula, Dundee, Inverness, Kirkwall, Stornoway and Sumburgh airports were shut to all but emergency flights at 00:01 on Thursday for 24 hours.
