Southwest Airlines experiences nationwide flight delays and groundings due to technical issues.

Southwest Airlines experienced a nationwide ground stop due to an intermittent technology issue caused by a firewall that went down, delaying over 1,800 flights and cancelling 11. More than 20 Southwest flights to and from Honolulu airport are currently listed as delayed, along with delays in Kahului, Lihue, Kona, and Hilo. The airline is urging customers to check their flight status and explore self-service options as they work to restore operations. This comes just four months after Southwest suffered a holiday meltdown where thousands of flights were cancelled or delayed.
