Alaska Air Resumes Flights After IT Outage Led to Grounding

Alaska Air Group Inc. continued to recover on Monday after temporarily grounding its entire fleet due to a data center equipment failure that affected several of the carrier’s key operating systems.

Eighty-three Alaska Air flights, or about 9% of its total, had been canceled as of midday, along with 22 at subsidiary Horizon Air, according to FlightAware data. More than 150 flights at the two carriers were grounded Sunday, the airline said.
