The Alaska Airlines outage on October 23, 2025, brought one of the nation’s busiest carriers to a sudden standstill. A critical systems failure forced Alaska Airlines to issue a nationwide ground stop, halting all departures for hours and leaving passengers stranded at airports across the United States.
The airline confirmed that the disruption was caused by an internal IT malfunction that affected multiple core systems, including flight dispatching, crew management, and check-in operations. Though the issue was resolved later in the day, the ripple effects extended well into the weekend, with delays and cancellations continuing at major airports such as Seattle, Los Angeles, Portland, and San Francisco.

How the Alaska Airlines Outage Began
The Alaska Airlines outage began around 3:20 p.m. Pacific Time when the airline detected a system-wide failure that impacted its internal operational software. Within minutes, the airline halted all flight operations as a safety precaution.
Passengers at airports across the country reported receiving sudden notifications of flight cancellations or indefinite delays. Gate agents informed travelers that the airline’s computer systems were offline, preventing boarding passes, flight plans, and crew assignments from being processed.
A spokesperson for Alaska Airlines stated that the issue was related to “network connectivity problems” that affected critical systems used to manage flights and schedules.
Scope of the Disruption
The outage led to a complete ground stop for Alaska Airlines and its regional partner, Horizon Air. By evening, hundreds of flights had been delayed or canceled. Passengers waiting in terminals described long lines, limited communication, and widespread confusion.
Reports indicated that:
- Flights were held on tarmacs for more than two hours before being canceled.
- Self-service kiosks and mobile check-ins were unavailable for most of the afternoon.
- The airline’s website and mobile app experienced intermittent outages.
- Crew scheduling systems were offline, preventing proper staffing and flight clearance.
Though the systems were gradually restored later in the evening, full operational recovery took more than 24 hours.
Airports Hit the Hardest
The Alaska Airlines outage primarily impacted airports in the western United States, where the airline has its largest presence.
Major airports affected included:
- Seattle-Tacoma International Airport (SEA): Alaska’s main hub saw the largest disruption, with dozens of flights grounded and passengers unable to rebook.
- Portland International Airport (PDX): More than half of Alaska’s scheduled flights were delayed.
- Los Angeles International Airport (LAX): Travelers reported waiting in line for hours to reschedule flights.
- San Francisco International Airport (SFO): Dozens of departures were postponed or rerouted.
- Anchorage (ANC): The outage also hit Alaska’s operations in its home state, stranding travelers across the region.
At its peak, more than 250 flights were affected, impacting tens of thousands of travelers nationwide.
Alaska Airlines’ Response
Alaska Airlines quickly issued a public statement acknowledging the outage and apologizing to customers for the inconvenience. The airline explained that the issue was not related to cybersecurity or a data breach but rather a “technical malfunction” within its internal operating systems.
The airline’s IT teams worked overnight to restore affected systems, while customer service teams rebooked passengers and arranged accommodations where possible. By early Friday morning, most systems were back online, but flight schedules remained heavily disrupted.
In a follow-up message, the company said:
“We know how frustrating this has been for our guests. Safety is our top priority, and we made the decision to ground all flights until we were confident our systems were stable.”
Passengers Face Chaos and Confusion
For travelers, the outage caused hours of frustration and uncertainty. Many passengers reported being stuck on planes that were unable to depart, while others spent the night at airports waiting for updates.
Some described the scene as “organized chaos,” with lines stretching for hundreds of feet at check-in counters. Others shared their experiences on social media, showing crowded terminals and stranded travelers sleeping on the floor.
One passenger in Seattle said:
“They kept saying the system was down, but nobody knew when it would come back. People were anxious because no flights were moving at all.”
Many travelers also complained about limited communication from the airline during the outage, saying that updates were sporadic and vague.
Why Airline Outages Are Becoming Common
This incident is the second major systems failure Alaska Airlines has suffered in recent months. A similar, though smaller, IT issue occurred in July 2025, which grounded flights for several hours.
Experts say the airline industry’s growing dependence on complex digital systems makes it increasingly vulnerable to large-scale outages. Airline operations rely on interconnected software for everything from ticketing and boarding to navigation and maintenance scheduling.
When one of these systems fails, even briefly, the effects cascade through every aspect of flight operations. Because airlines run on tight schedules, even a few hours of downtime can create a massive backlog.
Impact on Travelers and the Economy
The Alaska Airlines outage caused more than just inconvenience. Thousands of passengers missed connecting flights, business meetings, and personal events. Some were forced to pay for hotel stays or meals out of pocket as they waited for rebooked flights.
The outage also had an economic impact:
- Local airports saw heavy congestion and increased staffing costs.
- Partner airlines were forced to accommodate displaced passengers.
- Food and retail outlets inside airports reported higher demand as travelers waited for updates.
Airlines typically spend millions in compensation and rebooking costs after large-scale disruptions like this. Alaska Airlines has said it will review requests for refunds or travel credits on a case-by-case basis.
Safety and Investigation
While Alaska Airlines confirmed that the outage was not caused by a cyberattack, federal aviation authorities have requested a review to ensure the integrity of the systems involved.
The Federal Aviation Administration (FAA) said it was coordinating with the airline to monitor the situation and ensure flight safety standards were met throughout the disruption.
In the meantime, Alaska Airlines has launched an internal investigation to determine what caused the outage and how to prevent it from happening again.
Lessons for Travelers
Airline IT outages are becoming more frequent across the industry, and experts recommend that travelers take a few precautions to minimize the impact of future disruptions:
- Always check flight status before heading to the airport.
- Sign up for text alerts from the airline for faster updates.
- Book early flights when possible; they’re less likely to be affected by later disruptions.
- Keep essential items—medications, chargers, snacks, and toiletries—in carry-on bags.
- Know your passenger rights, including compensation and rebooking options during major delays.
While outages like this are rare, being prepared can help travelers handle disruptions with less stress.
What Happens Next for Alaska Airlines
Alaska Airlines has stated that it expects to resume normal operations by the weekend. However, passengers should still anticipate residual delays as the airline works through the backlog of flights and displaced passengers.
The company plans to conduct a full systems audit to identify weaknesses and prevent similar failures in the future. Industry analysts say Alaska will need to rebuild passenger confidence, especially after experiencing two major outages in less than six months.
Despite the chaos, the airline emphasized that safety remains its highest priority:
“We grounded our fleet because safety always comes first. We will continue working around the clock to ensure this does not happen again.”
Final Thoughts
The Alaska Airlines outage serves as a reminder of how dependent the modern aviation industry is on technology — and how vulnerable it can be when systems fail. For passengers, the experience was frustrating, but it also underscored the importance of safety and the airline’s decision to ground flights rather than risk operational instability.
As Alaska Airlines works to restore normal operations and prevent future outages, passengers and industry watchers alike will be keeping a close eye on the company’s response.
