Mar 2, 2018

I was traveling with a 20-month old who had her own seat. Unfortunately when the seat arm was up it still stuck out to a degree that she couldn't lay across to nap. I would fly Frontier alone without having to pay extra for seat assignments but will not choose this airline when flying with a toddler.
