‘Unacceptable’: Southwest airlines flight disruptions lead to chaos and US inquiry

The airline cancelled about 8,000 flights, stranding customers and leading to hours-long queues to speak with overworked staff

The US Department of Transportation will examine thousands of flight cancellations by Southwest Airlines over the holiday weekend, a massive disruption which left thousands of holiday travelers grounded, even in areas of the country not suffering from winter storms.

In a tweet on Tuesday, Joe Biden said: “Thousands of flights nationwide have been canceled around the holidays. Our administration is working to ensure airlines are held accountable.”
