This rule only applies to a single adult + child pair, and not the entire traveling party. For instance, if you have a party of 1 child and 2 adults, the airline is well within its rights to charge seat selection fees to the second adult. It’s incredibly frustrating that I have to pay an extra $40-$50, per journey, to United to sit next to my wife and child. And that’s with the current “consumer friendly” rules in place.
