Travellers are being advised to check the small print of their travel insurance to ensure they are covered for strike action.
Air passengers are most likely to be affected by industrial action at airports in Germany, Italy and Spain this week.
EssentialTravel.co.uk head of sales Stuart Bensusan warned consumers to check travel insurance terms and conditions.
“Cover does exist for holiday abandonment, missed departure and travel delay as a result of the strike action,” he said.
“However, only customers who book their insurance prior to the announcement of the dates will be covered fully, as per their terms and conditions.
“Anyone purchasing travel insurance after the strike dates are announced will be fully covered under medical and baggage but are unlikely to be covered for travel delay, travel abandonment and missed departure due to strike action, although we advise checking individual policy wording.”
He added: “Those who have already purchased travel insurance should check the terms and conditions of their policy in order to understand properly what they are and aren’t covered for, and we urge those that haven’t yet booked insurance to do so before more potential strike dates are announced this summer to ensure cover.”
