Chase says that part of my benefits with my Southwest Chase credit card is 2 free Early Bird Checkins per year. But they give no information on how you accomplish this. Anybody know?

Does it work like the UA Chase deal with renewal of Pre-Check where they give you a credit for the $85 when you charge your Pre-Check fee to your UA Chase card?

So I would charge the Early Bird to my Southwest credit card and Chase would give me a credit for what I paid? Or it works some other way?
