British Airways ran a full long-haul service from Heathrow today as it waited for a court decision on whether a planned strike by its cabin crew will remain outlawed.
The airline, which won an injunction against the Unite union on Monday, said its global operation started well today.
The union has appealed against the injunction, with the court's decision due to be announced tomorrow.
BA said: "We are operating a full schedule at Gatwick and London City and a full long-haul schedule at Heathrow. We are operating just over two-thirds of our short-haul programme at Heathrow and we will continue to reinstate further flights where we can.
"Whilst we await the outcome of Unite's appeal to overturn the High Court injunction against the strike, we are unfortunately unable to return to a full schedule. We would like to apologise to our customers for the inconvenience during this difficult period.
"We will update BA.com with the latest information for our customers. Customers who do not have a confirmed booking should not go to the airport."
Unite had planned a series of five-day walkouts from yesterday in a long-running row over jobs, pay and working conditions.
