British Airways said its services were due to return to normal on Monday (28 February) after suffering a major IT failure over the weekend.
The airline had to cancel all short-haul flights from Heathrow on Saturday (26 February) morning due to a technical failure with its systems. Long-haul services continued to operate but with some delays.
The IT problem, which BA stressed was not caused by a cyber attack, was resolved on Saturday, although there continued to be some cancellations and delays to services throughout the rest of the weekend.
Flights from Gatwick and London City airports also suffered some delays because of the IT issues. More than 500 BA flights were either cancelled or delayed over the weekend.
BA said in a statement on Monday: “We are planning to operate our normal schedule today, and we're working hard to make sure our customers are able to seamlessly travel through the airport to get them on their way as quickly as possible.”
