British Airways was hit by a worldwide computer system power failure on Saturday, causing cancellations and delays for thousands of passengers. More than a third of British Airways flights from Heathrow were cancelled on Sunday. All long-haul services left from Heathrow, but with delays, BA said.
The airline has urged people to check the status of flights before travelling to the airport.
On Monday, BA said, “As our IT systems move closer to full operational capacity, we will again run a full schedule at Gatwick and intend to operate a full long haul schedule and a high proportion of our short haul programme at Heathrow. Our terminals at Heathrow are still expected to be congested so we ask that you do not to come to the airport unless you have a confirmed booking for today and know that your flight is operating.
If you are due to fly on Monday 29 May and no longer wish to travel, even if your flight is still operating, you can claim a full refund via our website/call centre or rebook to travel up to the end of November.
If you need to rebook your flight we strongly recommend using ba.com or the call centre rather than travelling to the airport to make any changes.”
The airline is liable to reimburse thousands of passengers for refreshments and hotel costs.
Customers displaced by flight cancellations can claim up to £200 a day for a room (based on two people sharing), £50 for transport between the hotel and airport, and £25 a day per adult for meals and refreshments.
