Most Southwest Airlines flights from RDU resume Monday

Some Southwest Airlines flights will resume at Raleigh-Durham International Airport on Monday after a winter storm kept flights grounded all day Sunday.

Officials said all Southwest Airlines flights, and about 20 others, were canceled at the Raleigh-Durham Airport on Sunday due to inclement weather.

The cancelation was due to icy conditions at the Terminal 1 gates, officials said. Most other airlines at the airport were operating on-schedule, but more than a dozen canceled their outgoing flights.

By Monday, only nine flights remain canceled. Eight of those are Southwest flights.

"Airport roadways are extremely slick due to the extreme cold temperatures," said airport officials. "Please exercise the utmost caution and greatly reduce driving speed [when driving on airport grounds]. Crews are on duty and are responding to trouble areas."

Officials continue to urge travelers to check their flight status with their airline.

The airport also expects reduced services from taxis, Uber, Lyft, hotel shuttle, car services, bus services and other ground transportation companies due to icy road conditions. Officials are asking all airport guests seeking transportation to see the guest services desk for assistance.

Officials said teams from RDU and Southwest are working together to get affected customers traveling as soon as possible.
