Some Southwest Airlines passengers will continue to feel the lingering impact of technical issues that prompted the airline to cancel around 500 flights on Tuesday, just a day after flights across the country were grounded for another technical issue.
“Although our tech issues for Tuesday have been resolved, we still experience a small number of cancellations and delays on our network as we continue to work to resume normal operations,” said Southwest spokesperson Dan Landson, at USA TODAY Wednesday morning.
The airline said Tuesday’s proactive cancellations were related to “intermittent performance issues” with its network connectivity, while Monday’s issues were related to a third-party weather data provider. Both issues are still being investigated by Southwest.
In the meantime, the airline is urging customers to check their flight status on Southwest.com or speak to customer service agents to help them with their travel needs.

The Dallas-based airline had reported that operations had returned to normal after Monday’s technical issues before encountering another issue with Tuesday’s “system glitch.” Southwest spokesman Chris Mainz said the company did not believe the two issues were related, but that Southwest was “looking into the matter to make sure.”
Southwest Airlines passengers were stranded for hours at airports across the country on Monday due to technical issues.
Landson of Southwest told USA TODAY that Monday night’s technical issues “were preventing the transmission of weather information necessary to safely operate” his aircraft.
“As the Southwest crews and the vendor worked to restore connectivity, we implemented a ground shutdown to protect the safety of our crews and customers,” he said.
FlightAware.com flight tracking website showed Southwest recorded 1,769 delays and 566 cancellations on Tuesday. As of Monday, there were over 1,450 delays.
People started social media posting Monday night that their flights were grounded, with some reporting that they had been told this was due to problems with the electronic system used to monitor the weather.
