I'm a bit confused and could use some advice.

I am traveling with my elderly mother (who needs a wheel chair) and my husband (my companion ticket).

I booked Wanna get away plus. I prefer early check in and have no issue paying for it but I also don't want to waste money. In addition, I have 2 free early checkins from my credit card.

How do I use the two free early checkins? And should I save them for when Mom isn't with me since she will be boarded early anyway?

This is my first flight with SW although I have another planned in a few months.
