I will be flying in to Madrid for a meeting. Then, afterwards going for three days to Barcelona. I return to Madrid the morning of my flight which is at 11:20AM. I see the flight from Barcelona to Madrid is 1hour and 30 minutes approximately. Should I fly to and from Barcelona? Or is there a bullet train or train that maybe better to use? What are my options? Is the terminal in Madrid for International far from the domestic Barcelona arrival terminal? Thanks.
