Delta Air Lines faces widespread flight cancellations after IT outage

Delta Air Lines struggled to restore normal operations on Sunday after last week’s crippling global cyber outage, canceling about 1,000 flights on top of the 3,500 it had already scrapped.

The Atlanta-based airline, which canceled just over a quarter of its schedule Sunday and delayed another 1,700 flights or 46 per cent, is facing ongoing operational problems caused by the outage’s impact on its crew tracking system.
