It's great for travel as it's easy to carry around, but it's not approved for use on an airplane. The label specifically says not to use it on a plane, actually, because it cannot be used with only a lap belt which is all an airplane has.
I have a radian for the younger child and a vest for the older. The radian folds so it fits in the overhead bin if you don't want to use it in the seat (DS slept better on one flight using lap belt only and he was secure enough in it, sleeping so not wiggling around). But it is HEAVY. I wasn't expecting how truly heavy it is. The vest is fantastic once they're old enough for it though. I take it everywhere!
It's a great next step from a car seat, so OP, if you're looking for a new option, I recommend the vest highly!
