Delta Air Lines continues to struggle with massive flight cancellations and disruptions on December 30, 2025, despite the Northeast storm clearing. Internal reports indicate these issues are operational failures linked to crew availability and exhausted reserve pools, not weather events, severely impacting major hubs like Atlanta and Minneapolis. Thousands of travelers are affected, with the U.S. Department of Transportation monitoring these 'controllable' cancellations. DAL's pre-market price is $69.60 (+0.10%).
