- A large computer failure affected Alaska airlines
- Its complete fleet was put to the ground and 11 flights were in the sky at the time
- This is not the first landing of the company’s computer fleet
Alaska Airlines flights are running after a mysterious computer failure anchored flights for several hours.
The breakdown led to the landing of all the flights of the company and affecting the Air Horizon flights – a subsidiary of the Alaska company.
In addition to the disturbances of the flight, residual delays are expected, because the airlines and crews of the airline are based on normal capacity.
Alaska Airlines it outrage
“It will take a while to bring our global operations back to normal,” said the company in a post.
It is believed that around 11 flights were in the air during the breakdown, which was resolved several hours after being detected for the first time.
No official explanation of the deep cause has been provided, but some signs point to the Ransomware Spider Spider group, which recently targeted other victims in the aviation sector, notably Qantas, Air Serbia and Westjet.
Hawaiian Airlines, who has also been under the ownership of Alaska since the end of 2024, also had a cyber-incident earlier this year.
In June 2025, Hawaiian Airlines shared in a post X: “Hawaiian Airlines addressed a cybersecurity event that affected some of our computer systems.”
For Alaska Airlines in particular, this marks the second landing linked to the computer fleet in just over a year. In April 2024, a problem with the system that calculates the weight and balance of planes also caused a complete setting.
Interestingly, Microsoft also said that it was undergoing “active attacks” on server software on July 20 (via PK Press Club), but few details have been shared concerning this incident. We do not know if the two incidents are linked.
Techradar Pro asked Alaska Airlines more information on yesterday’s incident, but we did not receive an immediate response.
