Alaska Airlines warns that more flight delays are likely after IT outage

Alaska Airlines warned Monday of further flight disruptions after an unexpected failure in a crucial piece of hardware caused it to stop all flights for three hours late Sunday.

As of 10:45 am, the Seattle-based carrier had cancelled 66, or 7%, of their scheduled flights. 110 flights, or 12% of them, were delayed. FlightAware data shows that the ET time zone is currently GMT. Horizon Air, a subsidiary of the company, was also experiencing flight delays.

The airline has cancelled more than 150 flights since Sunday night. It was prompted to request an all-system ground stop on Alaska and Horizon Air at 8 p.m. Pacific Time. Around 11 p.m. PT, its operations were resumed.

Alaska Airlines said that additional flight disruptions were likely due to the repositioning of aircraft and crews across its network. The IT outage has nothing to do with any current events and is not a cyber event.

A critical piece of hardware in its data centers was unexpectedly faulty. It was manufactured by a third party. Alaska said that the failure affected several of their key systems and required a ground-stop to maintain aircraft position.

It said that it was working with its vendor to replace hardware at the data centre, but did not specify the location. Reporting by Rajesh Kumar Singh and David Shepardson in Chicago; editing by Aurora Ellis
