iflyswa.com has always redireced to southwest.com for me in the past. I just tried it and it redirected to souhwest.com again. Not sure what is going on with your machine, but as the other poster suggested, just go to southwest.com
It is also working properly for me as well. As was mentioned, I would recommend using the app or southwest.com. Also note that you might clear your browser's cache or try a different one if you want to continue to use the iflyswa.com route.
