It becomes a bad idea when you think it will allow you to go where you should not go. Most of the time it's not the burial that kills you, its the trauma from the rocks, trees etc.
Ya but if that's your thinking you have no business in avalanche terrain at all, airbag or not.
A general part of terrain choice is level of danger and exposure below. If you feel there is a pretty good chance of things moving than you don't go putting yourself out over death exposure. The airbag comes in real handy it seems when you have a nice wide open run out though, I saw a kid get slid in Jackson my last trip there in a chute called M&M and he used his airbag and came out on top. It wasn't a little slide either. It runs out into the upper bench of Rock Springs which is mostly very clean.
