So first you would put your phone in airplane mode. Once in airplane mode turn on your Wi-Fi and select the Southwest WiFi. You should be redirected to the Southwest entertainment portal or it might redirect you to a place to copy a link which you can paste in to a web browser.
***If you want to watch free movies on the plane you will need to have the Southwest mobile app on your phone (be sure you download before you fly)***
If you want to connect to the internet you can do that from the entertainment portal for $8 for an all day pass (yep $8 gets you all flights including connections for that day)
You can learn more Here and Here
*southwest planes don't have charging plugs so I would bring a power bank or 2 as your phone can die quickly using the movies or WiFi.
