(Reuters) — The U.S. Transportation Department said late on Monday it would examine the large number of Southwest Airlines cancelled and delayed flights in recent days to determine if they were in the airline’s control, calling them “unacceptable.”
Southwest canceled 2,886 flights on Monday, or 70% of scheduled flights, after cancelling 48% on Sunday, according to flight tracking website FlightAware. It has also already canceled 60%, or more than 2,400, of its planned Tuesday flights.
“USDOT is concerned by Southwest Airlines’ disproportionate and unacceptable rate of cancellations and delays as well as the failure to properly support customers experiencing a cancellation or delay,” the department said.
It said it would “closely examine whether cancellations were controllable and whether Southwest is complying with its customer service plan as well as all other pertinent DOT rules.”
Southwest declined to comment late on Monday on the USDOT statement but pointed to a statement it issued earlier offering “heartfelt apologies” and said “with consecutive days of extreme winter weather across our network behind us, continuing challenges are impacting our customers and employees in a significant way that is unacceptable.”
The airline added it was working “to urgently address wide-scale disruption by rebalancing the airline and repositioning crews and our fleet ultimately to best serve all who plan to travel with us.”
Other major U.S. airlines suffered significant cancellations in recent days but not nearly at as high rates as Southwest and they have now largely recovered.
The Transportation Department on Monday pointed to the Southwest Airlines customer service plan, which notes the airline will provide meal or hotel vouchers for extended delays that are due to issues within the airline’s control but not for unforeseen issues like weather.
In August, major U.S. airlines including Southwest told the DOT they would commit to provide meals for customers delayed by three hours and hotel rooms for stranded passengers if prompted by issues under the airlines’ control.
Many airlines have previously offered vouchers or hotel rooms for delays they caused but did not spell out all commitments in customer service plans.
