In August 2016, Delta cancelled over 2,100 flights after a power outage shut down the company’s computer system. As well as refunds and additional staff salaries, Delta also offered tens of thousands of delayed customers a $200 travel voucher in an attempt to limit the inevitable reputational damage cause by such an incident.

Their 5 hour outage ultimately cost them $150m. This figure shows how much of an impact even a small amount of IT downtime can have on an organisation. When it comes to air travel, arguably the biggest impact of downtime is the knock-on effect it has. The cancellation of a single flight affects availability of aircraft and crew, and also causes a ripple effect amongst other scheduled departures. A relatively small issue can take days to resolve – as we saw with Delta.
