We blogged last month about the IT outage at Delta Airlines which led to the suspension of flights across the US, Japan and Europe. Although the actual IT outage only lasted for 5 hours, disruption to flights persisted for several days and, in a briefing to investors on Wednesday, Delta estimated the cost of the incident at $150m. Sadly they did not give any breakdown of these costs.
Meanwhile, continuing the ongoing theme of IT problems at airlines, BA was in the headlines last week after a problem with its checking-in system. There were long queues at a number of airports, and passengers posted pictures of hand-written boarding cards; but BA stresses that no flights were cancelled.
