Do all Airbus jets have this adaptor, or just the US Airways version?
I have flown America West for years, but I have never noticed this adaptor (Of course, I have never looked for it either). If not, then the question is,

Are you on a US Airways jet, or an America West jet?

I have not flown in the last few weeks, so I don't know if they are keeping the fleets seperate.
