Yeah, I think it is one of the best policies around. When I was a gate agent for AirTran we had other airline FA's come up to the counter to fill out a jumpseat form, but they had to occupy a passenger seat only. I know that most airlines don't do this because that airline FA has not been trained on that particular airlines evacuation commands and procedures. In my opinion, we're all FA's, we know how to evacuate an aircraft.
Thanks for letting me know,
