Thousands caught up in Hial strikes disruption
A series of strikes affecting six Scottish airports has disrupted the travel plans of as many 5,000 passengers.
Air traffic controllers employed by Highlands and Islands Airports Limited (Hial) have taken the action in a dispute about their pay.
The first of three 24-hour strikes was held at Inverness Airport on Sunday.
Sumburgh and Kirkwall airports were shut on Monday and Dundee, Stornoway and Benbecula airports on Tuesday.
A total of more than 100 flights have been cancelled. The number includes 74 operated by airline Loganair.
The controllers' union Prospect said the strikes were "a last resort".
Hial's managing director Inglis Lyon has apologised for the disruption to passengers.
The Scottish government, which owns Hial, has urged the company and Prospect to hold fresh talks to resolve the dispute.
