If in fact AA switches to Piper Heidsieck, I think they may employ similar strategy to minimize waste.

The ORD FL indeed serves two Piper's.....when I was there last time, one was Piper Heidsieck (red bottle), the other was the CA produced Piper-Sonoma.

On a side note:

I wonder if many will even know the difference between:

Piper Sonoma
Piper Heidsieck
Heidsieck Monopole
Charles Heidsieck
