British Airways Have Canceled Flights After Computer Failure

British Airways has cancelled all flights from Heathrow and Gatwick because of global computer problems.

A "major IT system failure is causing very severe disruption to our flight operations worldwide", the airline said.

It apologised for the "global system outage" and said there was no evidence of a cyber attack.

The GMB union has suggested the failure could have been avoided, had the airline not outsourced its IT work.

Heathrow Airport has said it was "working closely" with BA to solve the issue.

Latest updates on BA flight disruption

All passengers affected by the failure - which coincides with the first weekend of the half-term holiday for many in the UK - will be offered the option of rescheduling or a refund.

The airline, which had previously said flights would be cancelled until 18:00 BST, has now cancelled all flights for Saturday and asked passengers not to come to Gatwick or Heathrow airports.

Other airlines flying in and out of Heathrow and Gatwick are unaffected.

The problems have affected BA call centres, the website and the mobile app.

Aviation expert Julian Bray said: "It's frozen the whole system so no British Airways plane can actually take off, they can't move the baggage, they can't issue passenger credentials, in fact they cant do anything at all.

"This is a very serious problem, they should have been able to switch to an alternative system - surely British Airways should be able to do this."

'Catastrophic'

Mick Rix, GMB's national officer for aviation said: "This could have all been avoided.

"BA in 2016 made hundreds of dedicated and loyal IT staff redundant and outsourced the work to India... many viewed the company's actions as just plain greedy."

BA aircraft landing at Heathrow are unable to park up as outbound aircraft cannot vacate the gates, which has resulted in passengers being stuck on aircraft.

Journalist Martyn Kent said he had been sitting on a plane at Heathrow for 90 minutes. He said the captain told passengers the IT problems were "catastrophic".

BA staff in Heathrow's Terminal 5 were resorting to using white boards, according to passenger Gareth Wharton.

Delays have been reported in Rome, Prague, Milan, Stockholm and Malaga due to the system failure.

Philip Bloom said he had been waiting on board a Heathrow-bound flight at Belfast for two hours.

He added: "We haven't been told very much just that there is a worldwide computer system failure.

"We were told that we couldn't even get on other flights because they are unable to see what flights we can be moved to."

As ever, it's a lack of information that's really making BA passengers angry….we're still awaiting an explanation from the airline and a timescale for how long the problems might last.

The GMB union says this meltdown could have been avoided if BA hadn't made hundreds of IT staff redundant and outsourced their jobs to India at the end of last year.

Yes, the union has a big axe to grind, but still, people will want to know if the airline made its IT systems more vulnerable by scaling back computer support to save money.

Although BA has just flatly denied it to me.

IT problems ripple through an airline.

If planes can't take off, they can't leave gaps at the gate for others to land.

If flights are delayed by more than around 5 hours, the airline must swap crews because shift lengths are strictly limited for safety reasons.

Telling customers to stay away is a drastic measure, but it's the only chance BA has off clearing the backlog of flights..
