Would it be possible to upgrade the seat selector tool to indicate where children and infants are currently seated?
I was just thinking travelling with my daughter (was lap, now seated) is great for me, but there are others who would prefer to be away from in children. In a similar vein, when travelling by myself, I would rather select a seat farther back/forward in Y if I know the front/back of the cabin is already full of kids.
It wouldn't need to ID people beyond that, just the age class of the seat.
