British Airways global systems outage that left it unable to allow passengers onboard and even track baggage for nearly three days was caused by an engineer who had switched systems off during maintenance work, the airline has said.
Speculation has raged over whether legacy systems or aggressive cost cutting had caused the crash that left thousands of airline passengers stranded at airports across the world last week. CEO Alex Cruz, who was appointed in April 2016, has strongly denied either were responsible for the situation, maintaining a power outage was the root cause.
The disruption to BA's operations last week has cost it an estimated $111 million including in lost revenue as well as claims the airline will have to face from outraged passengers.
BA parent IAG's stock value plummeted 150 million sterling in the first day of trading in London after the incident; where it is also listed in Madrid, IAG's value fell 350 million the day after the outage erupted.
