British Airways CEO Alex Cruz is promising customers it won’t happen again. May 27, at the onset of a week-long school vacation, a power surge hit the airline’s computer systems, taking out even its redundancies. The call center, website, and check-in computers went black, 800 flights to or from Heathrow and Gatwick were canceled, and 75,000 passengers were stranded. It was initially estimated the airline would lose $68 million on refunds and more for booking passengers in hotels. Most systems were operating again the following Monday, but the airline had to rebook customers and reconnect them with their baggage. Cruz dispelled rumors that the surge was due to any of the company’s cost-cutting measures. Back in September, 157 BA flights were delayed due to a computer glitch. Around the same time, IT glitches caused Delta Airlines to cancel 2,300 flights; Southwest Airlines, more than 2,000.
