An Alaska air carrier that suffered a cyberattack has experienced more disruption than initially projected.
The RavnAir Group on Dec. 20 experienced what it called a “malicious” cyberattack on its information technology network.
The company canceled some Alaska flights of Dash 8 aircraft and said passengers could expect more schedule changes.
On Monday, the company announced the disruption was worse than initially reported. Restoration of systems could take up to a month, the company said.
Additional flight cancellations and delays are possible for the group’s three airlines, RavnAir Alaska, PenAir and RavnAir Connect, the company said, according to Anchorage TV station KTVA.
The company is working with the FBI, a cybersecurity company and others to restore systems.
Some passengers will not be affected. For canceled flights, Ravn is rebooking passengers on other flights when possible.
