Another perspective here. I agree that "ideally" yes it would be great to have a carseat but that's no guarantee that your child will sit in it. This past September we got a carseat for my 2y/o and she ABSOLUTELY REFUSED to sit in it. I didn't expect that since she sits in a carseat in the car but hey -- go figure. She just threw a huge fit. It was an overnight trip and so for the sake of everyone on the plane she sat and, luckily, mostly slept in her own seat.
Believe me, I understand the potential danger and all that, I'm just telling you that listening to her scream in a small enclosed place for hours at a time didn't seem exactly "safe" either. Hopefully your LO will be more cooperative.
