Alaska Airlines Restores Flights After IT Outage Triggers Nationwide Ground Stop

A failure at its primary data center forced the halt, with residual cancellations expected as the schedule is rebuilt.

Overview

  • The FAA ground stop requested by the carrier was lifted at 11:30 p.m. Pacific time, allowing operations to resume after hours on the ground.
  • Alaska initially reported at least 229 cancellations, with later company tallies exceeding 400 and disrupting tens of thousands of travelers.
  • The stoppage covered both Alaska and regional subsidiary Horizon Air, and the airline says delays will persist as it repositions aircraft and crews.
  • The outage began around 3:30 p.m. Pacific time at the primary data center; the company says it was not a cybersecurity incident and flight safety was not compromised.
  • Alaska activated a flexible travel policy and postponed its earnings call, and it plans IT upgrades with outside experts after a second major outage this year as shares fell about 6%.
