Have a question regarding arrival and transfer information at Barcelona terminal 1 . I arrive on United airlines from EWR (with a USA passport) I'm transferring to Madrid via Iberia and wanted to find out how long I should time the connection.. do I need to clear any formalities and re-check in or is there a way of transferring in the sterile area? I will have carry-on and will arrive approximately 9 AM from EWR and curious to know how long I should time the connection. Is there a lounge I'm star gold and priority pass that I could use to take a shower on arrival if not it's not that important but I'm more concerned about the transfer in the process. Thanks
