Finnair has cancelled around 100 flights tomorrow (2 July), including two morning departures to London Heathrow and Edinburgh, due to strikes at Helsinki-Vantaa Airport.
The strike by the Finnish Aviation Union (IAU) will affect around 7,000 travellers, Finnair said.
Affected customers will be contacted by the airline, which is also allowing anyone booked to travel on 2 July to change their flight date free of amendment fees. Alternatively, customers can cancel with a full refund.
The IAU has also announced industrial action on 4, 7, 16, 18, 21 and 23 July, although details of cancellations are yet to be announced.
There have been numerous strikes at Helsinki airport this year, including one in May, which resulted in more than 110 cancellations, including multiple UK flights.
