American Airlines canceled another 634 flights on Sunday, more than 12% of its total operations for the day, the company said Sunday.
The airline has now canceled more than 1,500 flights since Friday, as it deals with weather issues and staffing shortages that started last week.
"With additional weather throughout the system, our staffing begins to run tight as crew members end up out of their regular flight sequences.
Two days of severe winds in Dallas-Fort Worth, its largest hub, sharply reduced arrival capacity, the company said.
