Low-cost carrier Norwegian has admitted that strikes earlier this year have cost the company around £29 million.
The airline had to cancel around 2,000 flights due to the industrial action by pilots in March.
The overall cost including having to spend around £9 million to look after stranded passengers, while loss of bookings cost Norwegian another £10 million.
CEO Bjorn Kjos said: “The strike among the Scandinavian pilots affected our company considerably and amounted to huge additional costs.
“Fortunately, we continue to attract many new customers in Europe and America, which offsets the fact that customers in Scandinavia were forced to fly with our competitors for a period of time.”
The strike led to reduction in Norwegian’s passenger numbers to 1.73 million during March – a 4 per cent fall compared to the same month in 2014.
