absolutely correct and speaking of the status earned on Iberia it would actually work for domestic US Travel since Oro and Platino status on IB is seen as Emerald and Sapphire tier meaning the ability to use Admirals Club and Flagship lounges. My father has done this before on Star Alliance ROP Plus Gold and AA domestic by using his Emerald Status from CX.
