British Airways passengers have expressed their anger at being unable to get through to the airline following the confusion over cancelled flights.
BA pilots are due to strike on 9, 10 and 27 September – but BA also told customers with tickets booked on other days that their flights were cancelled.
The company admitted on Saturday that it had told some passengers, by mistake, to rebook or get a refund.
It said those who booked other flights could claim the extra costs back.
However, it has not commented on how many customers have been affected, or the reason for the error.
BA also said it received nearly 40,000 calls in the first 24 hours and was working around the clock to help fix people’s problems.
