BA says 'power supply issue' behind IT failure that grounded flights

The carrier, part of the International Consolidate Airlines Group (ICAGY) , had hoped to clear the system failure, which developed early Saturday morning, and clear passengers from both London airports after 6pm BST.

The airline operates hundreds of flights out of the two airports on a typical day.

The airline posted a statement on its website on Sunday saying "although some of the IT systems have returned, there will be some knock-on disruption to our schedules as aircraft and crews are out of position around the world". He said the problems seemed to stem from a power supply issue, and noted that there was no evidence of a cyber attack.

British Airways has resumed some flights from London after a global computer sowed chaos, leaving planes grounded and thousands of passengers queuing for hours.

The airline said it was "extremely sorry" for the "huge disruption" it cause and that its engineers were continuing to work hard to restore its services.

The airline said most long-haul flights due to come to the airports on Sunday would arrive as expected but there would be further delays and disruption to its services.

British Airways GMB union has blamed the airline's 2016 decision of outsourcing IT jobs to India as the reason behind cancelling all Saturday flights from London's two biggest airports: Heathrow and Gatwick.

Cruz thanked BA customers for showing "great patience", and said that all passengers who decide to cancel their flights will receive full refunds.

BA advised customers to continue checking the status of their flight on its website before travelling to the airport.

There were chaotic scenes at the Gatwick and Heathrow as people tried to make their way overseas for the long weekend and half-term school holiday. The pilot said passengers on planes that have landed at Heathrow were unable to get off because there was nowhere to park.

British Airways had apologized for any problems whilst Heathrow have asked for more customer service worker to aid ease the trouble.

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

In addition to the aftermath of the BA meltdown, European air travellers have the added inconvenience of a strike by Italian air traffic controllers and some Alitalia staff on Sunday.
