US Air seat power

Has anyone flown on US Air and used their seat power.

What I could find on their web site is a little vague.

Thanks

I flew on 3 A320s and 1 B757 and there was none on any of the aircraft.

I get the impression it is only on the ex US Airways aircraft as all of mine where ex America West.

Yup just flew several legs on US Air/Alaska/AmericanWest and no seat power to be found. On some flights no audio let only visual in Domestic First!
