An unforeseen technology failure caused a major disruption in Alaska Airlines’ operations on Sunday evening, leaving passengers stranded across the United States. All flights were temporarily halted due to an IT outage, causing confusion and delays for travellers. The airline has since resumed operations, but residual impacts are still being felt.

Unexpected Outage Grounds Entire Fleet

The issue began around 8 p. m. Pacific Time when Alaska Airlines reported an IT outage that affected their operational systems. In response, the airline issued a temporary ground stop for all Alaska and Horizon Air flights until the problem was resolved. The Federal Aviation Administration (FAA) confirmed the halt, which included all aircraft operated under both airlines. This caused over 280 aircraft to be grounded, impacting more than 120 destinations across five countries.

Operations Resume, But Disruption Continues

The airline lifted the ground stop at 11 p. m. Pacific, stating that operations had resumed. However, they warned of continued disruption throughout the evening and into the next day. Passengers were advised to check their flight status online and allow extra time at the airport. The airline also recommended keeping receipts for potential reimbursement of expenses such as hotel stays or alternative transportation.

Delays, Cancellations, and Confusion

The IT outage affected hundreds of flights nationwide, with major airports such as Seattle-Tacoma, Portland, and Denver experiencing the disruption’s impact. Passengers reported delays and limited communication from staff during the halt. At Denver International Airport, some travellers were stuck on the tarmac for two hours before being told they had to exit the plane.

Wider Questions About Airline Tech

This is not the first time a technology glitch has caused issues for a major US airline. In 2022, Alaska Airlines experienced a similar disruption, and last month, its subsidiary Hawaiian Airlines reported IT system problems following a cyberattack. This raises concerns about the reliability of airline technology and the potential for future disruptions.

Travellers Left in Limbo

Although operations have resumed, travellers are still experiencing delays and cancellations as the airline works to reposition crews and aircraft. Passengers are encouraged to check for updates on the airline’s website or mobile app and contact customer support for rebooking if necessary. Alaska Airlines has apologised for the inconvenience and is working to resolve the situation.

What’s Next for Travellers?

As of now, operations are stabilising, but residual delays may continue into the early part of the week. The airline advises checking flight status and contacting customer support for rebooking if necessary. Their X (formerly Twitter) states that operations have resumed, but travellers should continue to check for updates. Alaska Airlines apologises for the disruption and is working to ensure a smooth travel experience for all passengers.
