Monday, July 21 – 11 a.m. Pacific Time
As of 11 a.m. on Monday, we continue to get our operations back on track at Alaska Airlines and Horizon Air following a significant IT outage that resulted in a system-wide ground stop of flights. The ground stop began around 8 p.m. on Sunday and was lifted at 11 p.m. Pacific.
A critical piece of multi-redundant hardware at our data centers, manufactured by a third-party, experienced an unexpected failure. When that happened, it impacted several of our key systems that enable us to run various operations, necessitating the implementation of a ground stop to keep aircraft in position. The safety of our flights was never compromised.
Since Sunday evening, we’ve had a total of nearly 200 flight cancellations. We’ve experienced 104 cancellations today, which have affected the travel plans of 13,500 guests. Additional flight disruptions are possible. There are also flight delays as we reposition our aircraft and crews.
The IT outage is not related to any other current events, and it’s not a cybersecurity event.
We are currently working with our vendor to replace the hardware equipment at the data center.
We appreciate the patience of our guests whose travel plans have been disrupted. We’re working to get them to their destinations as quickly as we can. If you’re traveling today, please check your flight status before leaving for the airport. Also, a flexible travel policy is in place to support our guests.
