US probes ‘unacceptable’ Southwest Airlines storm cancellations

Al Jazeera :
The United States Department of Transportation has said that it plans to examine mass flight cancellations and delays by Southwest Airlines in recent days, amid a devastating storm that has disrupted travel plans for millions of Americans during the holiday season.
The government agency said it would look to determine if the flight cancellations by Southwest – which in particular has faced flak from passengers online – were in the airline’s control, calling them “unacceptable”.
“USDOT is concerned by Southwest’s unacceptable rate of cancellations and delays and reports of lack of prompt customer service. The Department will examine whether cancellations were controllable and if Southwest is complying with its customer service plan,” the Transportation Department tweeted.
A powerful winter storm resulted in airlines cancelling thousands of flights over the long Christmas weekend. At least 48 people have died as large parts of the US battle frigid conditions.
