Delta cancels hundreds more flights in struggle to recover from Microsoft outage

Delta Air Lines CEO Ed Bastian apologized and offered frequent flyer miles to travelers for thousands of flight cancellations as the carrier struggled to recover from Friday’s globe-spanning IT outage, disruptions that sparked criticism from Transportation Secretary Pete Buttigieg.

The Atlanta-based airline canceled over 4,600 flights from Friday through Sunday, more than any other airline, according to aviation data firm OAG.

On Monday morning, Delta had already canceled another 700 flights, or 19% of its mainline operation, making up more than half of cancellations in the U.S., according to flight tracking site FlightAware.

The delays and cancellations have put Delta in a rare spotlight for the carrier whose leaders pride themselves on reliability and punctuality.
