Southwest Airlines Leaves Thousands Of Passengers Stranded

Federal regulators say plane problems and staff shortages caused the disruptions.

Southwest Airlines canceled hundreds more flights Monday following a weekend of major service disruptions.

According to Flightaware, the carrier has canceled 348 flights Monday and delayed another 271 flights.

The Dallas-based airline had blamed air traffic control issues and weather for its weekend "operational challenges" that saw over 1,000 canceled flights on Sunday alone. Southwest Airlines was the only airline to report the issues on that scale.
