I have a question regarding the use of the Miró lounge at BCN. My wife and I will be arriving in the morning on Singapore first class. We will then be leaving the airport to spend the day in Barcelona. That evening we fly to Rome on a Vueling flight. First question: can we use the Miró lounge immediately after arrival to take a shower? Second question: would that imply not being able to pick up luggage before we use the lounge, as we probably cannot get back into lounge after leaving secure area? Third question: would we be able to use the Miró lounge again, or any other loung just by showing our previous SQ first class boarding pass even though we will be departing on Vueling?
