WASHINGTON, June 26 (Reuters) - Hawaiian Airlines said

on Thursday that some of its IT systems were disrupted by a

hack, adding its flights were operating as scheduled.

In a statement, Hawaiian Airlines said "some of our IT

systems" had been affected by a "cybersecurity event." The

nature of the event was not disclosed, but that kind of language

is typically used in cases of ransomware incidents, where

digital extortionists paralyze a victim's computer network until

a cryptocurrency ransom is paid.

The airline, which is owned by Alaska Air Group ( ALK ),

said it had "taken steps to safeguard our operations, and our

flights are operating safely and as scheduled."

Reuters could not immediately ascertain the extent of the

disruption at Hawaiian, but a representative responded using a

Gmail address when contacted to seek further details.

The Federal Aviation Administration said its safety office

responsible for airline oversight is in contact with Hawaiian

Airlines. "There has been no impact on safety, and the airline

continues to operate safely. We are monitoring the situation,"

the agency said in a statement.
