Willie Walsh has defended the airline's handling of the flight chaos it suffered at the weekend, which left thousands of passengers stranded.
Mr Walsh, appearing in public for the first time since the incident, said he was “pleased” with how the airline had dealt with the disruption that grounded 75,000 passengers.
“I think the team under the leadership of [BA chief executive] Alex Cruz has done everything possible to get it back to flying a full schedule as quickly as possible,” he said.
“We know the cause of the problem. It was not about IT. The problem was caused by the failure of electricity power to the IT systems."
