Hawaiian Airlines, the tenth-largest commercial airline in the United States, is investigating a cyberattack that has disrupted access to some of its systems.

With over 7,000 employees, 235 average daily flights, and a fleet of over 60 airplanes, Hawaiian Airlines connects Hawai'i with 15 U.S. mainland cities and 10 other destinations across Asia and the Pacific.

The airline stated in a statement issued on Thursday morning that the incident didn't affect flight safety and has already contacted relevant authorities to assist in investigating the attack.

Hawaiian Airlines also hired external cybersecurity experts to asses the attack's impact and help restore affected systems.

"Hawaiian Airlines is addressing a cybersecurity event that has affected some of our IT systems. Our highest priority is the safety and security of our guests and employees. We have taken steps to safeguard our operations, and our flights are operating safely and as scheduled," the airline said.

"Upon learning of this incident, we engaged the appropriate authorities and experts to assist in our investigation and remediation efforts. We are currently working toward an orderly restoration and will provide updates as more information is available."

A banner on the airline's website notes that the incident hasn't impacted flights in any way and that travel hasn't been affected.

The same alert is also displayed on the Alaska Airlines website, which is owned by Alaska Air Group, a company that acquired Hawaiian Airlines last year.
