Air travel across the United States faced major disruption early Friday after Alaska Airlines grounded all flights nationwide due to a widespread information technology outage that brought the carrier’s operations to a standstill. The Seattle-based airline confirmed that the system failure has affected multiple facets of its network, including flight scheduling, check-ins, and dispatch coordination, forcing the temporary suspension of all departures until further notice.
The outage reportedly began in the early morning hours, with passengers across major airports—including Los Angeles, Portland, and Seattle—reporting delays and cancellations. Airlines depend heavily on integrated digital systems for managing flight plans, crew assignments, passenger check-ins, and aircraft tracking. Even a brief interruption in these systems can create a chain reaction that disrupts thousands of travelers nationwide.
Alaska Airlines, which operates one of the largest domestic networks in the western United States, has been working with its technical teams to identify and resolve the source of the failure. The Federal Aviation Administration (FAA) has been notified and is coordinating with the airline to ensure safety and manage air traffic flow during the suspension. While details on the root cause remain unclear, the issue appears to have affected both the airline’s internal infrastructure and certain customer-facing systems, such as mobile boarding and reservation tools.
Passengers stranded at airports have been advised to check Alaska Airlines’ website and social media platforms for updates. However, with the airline’s digital operations impacted, information flow remains limited. Customer service lines have been overwhelmed, and airport agents are handling rebooking manually where possible.
The incident highlights the growing dependence of the aviation industry on complex IT systems and the vulnerabilities that accompany that reliance. Similar outages have previously impacted other major carriers, including Southwest Airlines and Delta Air Lines, leading to widespread delays and cancellations that took days to recover from.
As of mid-morning, Alaska Airlines had not provided an estimated time for the resumption of normal operations. The airline assured passengers that safety remains its top priority and that all aircraft will remain grounded until systems are fully restored and verified. Travelers are being urged to monitor their flight status closely as updates are expected throughout the day.
The full scope of the disruption—and its potential impact on connecting flights and partner airlines—will likely unfold over the coming hours as Alaska Airlines works to bring its network back online.
