Saint Evil -Touché - attitude based on your organ grinder, monkey comment.
The CAA and FAA have different policies - CAA you would get a lap belt extender. FAA you dont. The only reason I got looked this up was that when I asked for a belt extender on an FAA regulated airline and was told that they did not carry them and to hold the infant. I now always buy a seat for junior and use the airlines CRS or our own approved car seat. Same rules apply for turbulance.
