British Airways resumes flights from London airports following global computer outage

The airline urged passengers to check their flight status online before travelling to the airport in a bid to avoid scenes seen over the weekend when people camped out at Heathrow.

However, BA said it would run a full schedule at Gatwick on Monday and it meant to operate a full long-haul schedule and a "high proportion" of its short-haul programme at Heathrow.

BA is liable to reimburse thousands of passengers for refreshments and hotel expenses, and travel industry experts have suggested the cost to the company - part of Europe's largest airline group IAG - could run into tens of millions of pounds. The airline said its terminals at Heathrow and Gatwick became "extremely congested" due to computer problems. But it blamed "knock-on effects of Saturday's disruption" for forcing to reduce Heathrow's short-haul schedule.

"Once the disruption is over, we will carry out an exhaustive investigation into what caused this incident, and take measures to ensure it never happens again", the airline's chief executive, Alex Cruz, said in a statement on Monday.

The airline is near full operational capacity following a power cut to its IT system that resulted in massive flight cancellations at Gatwick and Heathrow.

More flights left Heathrow as the day wore on, but most were operating with delays. There is one British Airways flight a day to and from the capital's airport.

British Airways has suffered other IT glitches recently, leading to severe delays for passengers in July and September a year ago.

Passengers scheduled to travel on flights on Monday have been told they can get a refund for their ticket, even if is scheduled to run, as have those expecting to get short-haul flights on Tuesday.

The UK carrier has scrapped nearly 600 flights since Saturday because of a computer failure and is still processing thousands of passengers who missed flights or lost their luggage.

Heathrow airport was hit the worst by the failure, with services from Gatwick expected to return to normal on Monday. That brings the total of flights scrapped at Heathrow and Gatwick airports since Saturday to 583, according to Bloomberg calculations.

On customer review site Skytrax, BA had a score of 5/10, with many reviewers saying they feel the airline's economy class on short-haul is now no better than a budget carrier.

BA said there was no evidence hackers had played any role in the outage, and denied claims by the union GMB that the problem may have been linked to the company outsourcing its IT work.

The GMB union said the airline's decision to outsource hundreds of IT jobs to India a year ago was behind the problems, the Guardian reported.

What does British Airways have to say?

British Airways continues to work in restoring its computer systems following a huge power failure that caused a huge disruption worldwide for thousands of its passengers.
