Alaska Airlines IT Outage Cancels 400+ Flights
Alaska Airlines says an IT failure on October 24, 2025 forced mass cancellations and an immediate systems review.
The Alaska Airlines IT outage on October 24, 2025 led to the cancellation of more than 400 flights and disrupted travel for over 49,000 passengers across the United States. Alaska Airlines (IATA: AS, ICAO: ASA) and regional partner Horizon Air (IATA: QX, ICAO: QXE) were affected after the Federal Aviation Administration (FAA) issued a temporary ground stop.
What happened during the Alaska Airlines IT outage
The carrier said the outage was not caused by a cyberattack. Alaska Air Group postponed its scheduled earnings call and warned investors of a material financial impact in the fourth quarter. Shares fell roughly 6% after trading opened following the disruption.
Alaska has committed to immediate upgrades to its IT infrastructure and has brought in external specialists to perform a full systems review. The move follows an earlier, separate disruption in July, prompting greater scrutiny of the airline’s operational resilience and back-office systems.
- Alaska Airlines IT outage: 400+ flights canceled and 49,000+ passengers affected.
- FAA-issued temporary ground stop impacted Alaska Airlines and Horizon Air operations.
- Alaska Air Group postponed its earnings call and forecasted a notable Q4 financial hit.
- Airline says outage was not due to a cyberattack and has hired outside experts for review.
Passengers faced delays, rebookings and long waits for customer-service assistance while operations teams worked to restore normal scheduling. Alaska did not release specific flight numbers tied to the cancellations, but the carrier emphasized safety and accurate passenger handling as teams prioritized recovery.
Industry watchers say repeated IT disruptions highlight broader tech risk in airline operations and the need for redundancy, faster incident response and clearer passenger communications. For travelers, the immediate lesson is to monitor flight status directly with the airline and register for real-time alerts.
