A computer-system outage grounded Southwest Airlines flights, causing delays for the second day in a row

• Southwest Airlines grounded flights on Tuesday due to an issue with its computer systems.
• Customers complained about delays on social media.
• The airline experienced a similar computer glitch that delayed flights by hours on Monday.

Southwest Airlines was hit with another system-wide computer outage on Tuesday, following similar issues Monday night.

The airline asked the Federal Aviation Administration to ground all of its flights in the contiguous US airspace over technology issues.

In a statement to Insider, Southwest said it is working to get operations back up and running.

"Southwest is in the process of resuming normal operations after a brief pause in our flight activity resulting from intermittent performance issues with our network connectivity Tuesday afternoon. Our Teams are working quickly to minimize flight disruptions and Customer impact," a spokesperson said.

The airline canceled roughly 500 flights during the outage, the spokesperson said.

Multiple US airports also released statements notifying travelers of the issues.

"Southwest Airlines is experiencing another multi-airport, system-wide outage currently affecting their phone and check-in systems," according to Orange County's John Wayne Airport.

The system outage comes after a similar issue delayed Southwest flights by hours on Monday night. Southwest had to ground all flights after a glitch meant that operators stopped receiving vital weather information. A company spokesperson told Insider at the time that its third-party weather data provider had "experienced intermittent performance issues."
