Connecting flights on IB Amsterdam to Seville via Madrid
My agent has booked me on flights that arrive into Amsterdam on Cathay Pacific. I have Emerald card. The connecting flight is booked with Iberia but the flight is actually operated by Vueling. I want to know that if I can use the lounge in both Amsterdam and Barcelona of Iberia as my flight has IB flight number on it and I am OW Emerald card holder.
