🛫 Alaska Airlines Grounds Fleet Nationwide Due to Major IT Outage
On July 21, 2025, Alaska Airlines and its regional carrier Horizon Air initiated a nationwide ground stop, leaving thousands of passengers stranded and disrupting flight schedules across the United States. The FAA confirmed the airline had voluntarily requested the stop due to a critical IT system outage affecting its operational systems.
From Seattle-Tacoma (SeaTac) Airport to LAX, the impact was widespread, triggering delays, cancellations, and confusion for both travelers and airport staff.
⚠️ Why Was Alaska Airlines Grounded Today?
The grounding was a result of an unexpected IT outage that crippled Alaska Airlines’ ability to manage flight dispatching, crew communication, and customer service tools. According to FAA statements, the Alaska Airlines ground stop was issued to ensure safety while the airline worked to resolve the issue.
“Out of an abundance of caution, we’ve paused all mainline operations until systems are stable,” Alaska Airlines announced early Monday.
📊 How Many Flights Were Affected?
- Over 46 Alaska Airlines flights canceled
- More than 300 delayed across the U.S.
- Major airports affected: SeaTac, Portland, San Francisco, LAX
Passengers reported long wait times at terminals, tarmac delays, and missing connecting flights due to the Alaska Airlines IT outage.
🧠 What Is an FAA Ground Stop?
An FAA ground stop is a directive that halts all aircraft from taking off. While it can be issued for severe weather, technical issues, or national emergencies, this time it was requested by the airline itself in coordination with the FAA to address the IT failure.
📍 SeaTac Airport Hit Hard
At the heart of this crisis was Seattle-Tacoma International Airport (SeaTac) — Alaska Airlines’ primary hub. With dozens of departures grounded, check-in lines stretched across terminals as travelers scrambled for updates and rebooking options.
🔁 Alaska Airlines Resumes Operations—But Delays Continue
By 11 p.m. PT, Alaska Airlines lifted the ground stop after restoring core systems. However, the airline warned travelers of “residual delays and cancellations” throughout the day as crews, aircraft, and schedules are reset.
🔐 Cybersecurity Concerns?
While Alaska Airlines has not confirmed a cyberattack, experts speculate that the IT outage may have stemmed from a network vulnerability or internal systems failure, raising alarms about cybersecurity in aviation. With previous data breaches and rising deepfake incidents, such IT collapses are becoming increasingly common.
🧳 What Should Passengers Do Now?
✅ Check your Alaska Airlines flight status before heading to the airport
✅ Visit the Alaska Airlines website or app for live updates
✅ Keep receipts for hotel, meals, or rebooking expenses for possible reimbursement
✅ If flying out of SeaTac Airport, allow extra time and expect long lines
