An Alaska air carrier that suffered a cyber attack has experienced more disruption than initially projected, according to a company announcement.
The RavnAir Group on Dec. 20 experienced what it called a “malicious” cyber attack on its information technology network, Anchorage television station KTVA reported.
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.
The company is working with the FBI, a cyber security company and others to restore systems.
Some passengers will not be affected. For canceled flights, Ravn is re-booking passengers on other flights when possible.
