Southwest Airlines issued a statement Wednesday about flight delays. As of 3:50 p.m. all but one of the Southwest flights in and out of Lubbock were listed as on time.  

Southwest said: 

Southwest Airlines began experiencing intermittent performance issues earlier this afternoon with multiple technology systems as a result of an outage. We are now managing flight delays across our system, with a temporary ground stop in place for those flights that have not left the gate. We apologize to our Customers whose travel plans are impacted. We have a Team of experts working diligently to resolve the technical issues and their efforts have systems gradually coming back online. We expect to continue our move toward a normal operation but believe it will take time. Updates will be posted on swamedia.com, our Southwest Facebook page and Twitter accounts.
