Is the 2016 Families Flying Together Act still in effect?

[NickB79]

My family and I are about to take our first-ever family vacation in March, flying from Minnesota to Tampa to escape this cold, snowy winter. Our daughter is 8 yr old, and we are flying Spirit Airlines, which is known for being stingy with basically everything.

My concern is that, unless I pay extra up front, my daughter may be seated separately from us. I don't care too much if she's with me or my wife, but I would not be OK with her not near either of us.

A coworker of mine told me that it was now law that children under 13 had to be seated near a parent, and that led me to the FFTA passed in the funding bill back in 2016. However, I can't find much more about it. Does anyone have more info on this, or experience with the situation I described above?

Thanks!
