Exactly! When my child was having his horrific tantrum, it happened to be during a very turbulent flight. The flight attendants told me he NEEDED to be strapped in. I had to physically pull his belt tight and hold my hand over the latch mechanism so he couldn't get out.
And let me just say for the record, in no way, shape or form did the flight attendants ever offer to "entertain" my child. Not even close. Gave me lots of sympathetic looks and they were never condescending, which is more than I actually expected. I was lucky to have a *VERY* kind and understanding man next to me who turned on his ipod for the entire time and acted like nothing was happening (this after I apologized profusely for my son's behavior

).
We are flying again in 2 weeks and initially when we booked our tix I didn't get any special seats. But AirTran bumped us from 2 different flights and in the course of talking to a SUPER nice agent about my son, it turns out her grandson has Sensory Integration Disorder like my son does, and she put us in the front row so he doesn't kick anyone's seat if he gets overwhelmed again. There are 6 seats in the front row and none had been taken so far, so I didn't feel bad about it. But of course if I saw a handicapped person I'd move out of there in a heartbeat. DH and DS will sit further back in 'regular' seats.
