For passengers, the outage brought stress and uncertainty. Many were left stranded at airports, unable to get clear answers about when flights would resume. Some travelers missed important events, while others faced unexpected expenses for hotels or meals.
“I was supposed to fly home to see my family, but my flight was canceled with no warning,” said one passenger at Seattle-Tacoma International Airport. “The lines were huge, and no one seemed to know what was going on. I just hope Alaska Airlines can help us get where we need to go.”
Alaska Airlines advised all passengers to check their flight status on the airline’s website or app before heading to the airport. The airline also encouraged travelers to contact customer service for rebooking or compensation options and to monitor official channels for the latest updates.
Broader Industry Context: A Pattern of IT Outages
This incident marks the second major IT-related grounding for Alaska Airlines in just over a year. In April 2024, the airline grounded its entire fleet due to a malfunction in the system that calculates aircraft weight and balance—a critical safety function. That event also led to widespread delays and cancellations, showing a troubling pattern for the airline.
In September 2024, Alaska Airlines faced another significant disruption at Seattle-Tacoma International Airport when an IT issue prevented customers from checking in through the app and website. These repeated problems have raised questions about the reliability of the airline’s technology and its ability to prevent future outages.
Other major airlines, including American, Delta, Southwest, United, and Qantas, have also reported IT disruptions in the past year. While no new incidents involving these airlines were reported in July 2025, the trend points to a growing vulnerability in the aviation sector as a whole.
Cybersecurity Concerns and Official Clarifications
The timing of the Alaska Airlines outage raised additional concerns because it happened on the same day Microsoft issued a cybersecurity alert. Microsoft warned of active cyberattacks targeting on-premises SharePoint servers, describing a “zero-day” exploit that could allow hackers to access sensitive data. However, Alaska Airlines made it clear that there was no evidence linking their outage to this or any other cybersecurity event.
“We have thoroughly investigated the incident and found no signs of a cyberattack,” the airline stated. “The outage was caused by a hardware failure, not by any external threat.”
Despite this reassurance, the incident has led to increased scrutiny of airline IT security protocols. As airlines rely more on complex digital systems, the risk of both technical failures and cyberattacks grows.
Industry Analysis: The Challenge of Modernization
Aviation analysts say that IT outages are becoming more frequent and disruptive as airlines modernize their operations but continue to depend on older systems and third-party vendors. Many airlines use a mix of new and legacy technology, which can create weak points in their infrastructure.
“Airlines are under pressure to invest in more robust, cloud-based, and cyber-resilient systems,” said one industry expert. “The goal is to reduce the risk of outages and minimize the impact on passengers. But upgrading these systems takes time and money, and there are no easy fixes.”
According to analysis by VisaVerge.com, the aviation sector’s growing reliance on digital technology means that even small failures can have huge consequences. The site reports that airlines must balance the need for innovation with the need for reliability and security.
