It comes after Unite members employed across the Highlands and Islands Airport Limited (HIAL) group rejected a 5% pay offer, with inflation standing at 13.4%.
The union represents security staff, baggage handlers, ground crew, fire and rescue workers, and people in administration roles.
Workers at Dundee airport will be the first to walk out, with teams set to strike for 24 hours on 17 February and again on 20 February.
This will be followed by action at a further 10 Scottish Highlands and islands airports over 21-23 February – Barra, Benbecula, Campbeltown, Inverness, Islay, Kirkwall, Stornoway, Sumburgh, Tiree and Wick.
Unite general secretary Sharon Graham said with inflation at a "generational high", HIAL’s "completely unacceptable" offer represented a substantial real-terms pay cut.
She laid the blame at the door of airport management and the Scottish government, which owns HIAL. Unite said the Scottish government was yet to meet directly with the union to discuss pay, recruitment, conditions and retention.
Unite industrial officer Shauna Wright said members deserved better, and warned of the impact on Scotland’s rural and island communities.
Unite members in December voted 73.5% in favour of outright strike action, and 92.8% in favour of action short of a strike "in a bid to improve pay for rural communities amid a cost of living crisis".
HIAL said: "We are currently liaising closely with our local teams and airlines to determine the impact of this industrial action and the potential disruption for passengers, and will post further updates and information on our website and airport social media channels.
"Meantime, we would advise passengers who intend to travel on these days to keep in touch with their airline."
