We are planning on traveling to Europe from the US with my toddler who will be 17 months old at the time of the trip. The flights have a 3 x 3 x 3 seating arrangement. We are thinking of buying him his own economy seat so we have a whole row to ourselves and a bit more room with him. He is under 2 and could theoretically fly as a lap infant. This set up is much cheaper than 2 business seats, which we also considered. My only question is do we have to bring his car seat? At our destination we don’t need it and I hate the idea of lugging it around everywhere for three weeks. Should we get one of those harnesses that clips onto the seat? I’ve heard that some airlines don’t allow you to use them.
