Hello guys, apologies if this has been covered before but couldn't find any info about this.
I'm about to transfer some BA avios to Iberia Plus and book an Iberia rewards flight on IB Premium economy from Madrid to New York. I have no status on Iberia and will be using Iberia plus to make the booking. Will I have lounge access at Madrid airport as I am a BA Gold bearing in mind my Gold card won't be registered in the booking being a Iberia Plus redemption flight?

Looking forward to your answers and advice.
Thanks all.
