UPDATE: Cyber attack on RavnAir forces cancellation of Alaska Dash 8 service

RavnAir Group says it will resume its normal afternoon Dash 8 flight schedule as of 1 p.m. Saturday after a cyber attack forced the air carrier's Dash 8 service offline.

Among the affected routes were Homer 870/871 and 874/875, Kenai 826/827 and 830/831, Aniak 816/817, Kodiak 890/891. Dutch Harbor 960/961 and 962/963, and St. Mary's 860/861 routes were canceled due to weather according to an update from RavnAir Group Saturday afternoon.

A RavnAir spokesperson says the company will attempt to add flights over the next two days to make up for canceled flights and book passengers on alternative flights.

Passengers are asked to check in as normal for all flights, and to contact the RavnAir Call Center with questions.

RavnAir Group says a cyber attack has forced the company to cancel Ravn Air Alaska Dash 8 flights Saturday, with additional cancellations expected.

According to a release from RavnAir spokesperson Debbie Reinwand, the cyber attack occurred on Friday.

The exact nature of the cyber attack has not yet been disclosed, but according to the release, forced the company to disconnect its Dash 8 maintenance system network as well as its backup system.

PenAir and RavnAir Connect flights are operating normally off of redundant backup systems according to the release.

As of 11 a.m. Saturday, 12 flights were cancelled affecting 260 passengers, with more disruptions expected throughout the day as IT teams and a cyber security contractor work to restore RavnAir's Dash 8 networks concurrently with a law enforcement investigation.

The RavnAir statement says Dash 8 flights were proactively canceled until 12 p.m. Saturday. Which Dash 8 routes were affected wasn't immediately known.
