Despite explanations and apologies, Southwest Airlines delays and cancellations caused by a computer glitch continued for the third day in a row.

“We extend a heartfelt apology to our Employees and our Customers who are inconvenienced by the disruption in service,” the company said in a statement. “We appreciate their patience as we continue our work to make this right.”

The company said that “more than 250” of its 3,900 daily departures were canceled. The flight-tracking website flightaware.com showed that number to be more than 300 and showed almost 400 delayed Southwest flights.

On Thursday in a video posted to Twitter, Southwest’s chief operating officer, Mike Van de Ven, said the airline was doing a “deep dive” to figure out why its computer systems failed.

In its statement, the airline pointed out that customers scheduled to travel between Wednesday and Sunday have two weeks from their original date of departure to rebook travel at the original fare for no additional cost.

Delays and cancellations persisted for Southwest Airlines customers around the country Thursday as the company dealt with the fallout of a massive computer glitch that occurred Wednesday.

For the most part, Southwest’s systems were back up Thursday morning, the airline said in a blog post — but the disruptions continued. By early afternoon about 400 Southwest flights had been canceled and another 400 were delayed, according to flight-tracking website flightaware.com, with the disruptions affecting about 20 percent of Southwest’s 3,900 daily departures. At Baltimore Washington International Airport, according to FlightAware, all of the day’s 44 cancellations came from Southwest; another 50 Southwest flights were delayed. At Reagan National Airport, there were nine cancellations so far Thursday — all from Southwest.

“I want to start off by once again apologizing to our Customers and reiterating that your experience throughout the past 24 hours is not the service you should expect from Southwest Airlines,” Southwest’s Linda Rutherford said in a company blog post, adding that “recovery will take some time.”

Passengers on Southwest Airlines are facing long lines, delays and some cancellations at area airports after a computer glitch.

The technical problem appeared Wednesday afternoon and affected flights for the airline throughout the country, causing delays. Their app and website were also down during the glitch.

On Thursday morning, photos on social media showed long lines of passengers at ticket counters and check-in lines at Southwest booths throughout the country.

According to FlightAware.com, about 170 Southwest flights across the country were canceled as of Thursday morning.

And even big wigs were stuck. On social media, a picture showed former presidential candidate and Maryland governor Martin O’Malley among those who were stuck at BWI Airport.
