There is one airport in Barcelona – Barcelona El Prat, located 12 km southwest of the city centre and handling both domestic and international flights, though the number of intercontinental flights is still relatively small. The authorities plan to build a few more terminals to handle the passenger traffic. Terminal 2 has its own commuter train station with trains running to the centre of the city every 30 minutes. Make sure to punch your ticket. This way you will be able to get to the central square and make connection to the subway station. Or you can take a scheduled private bus line (Aerobus) that will get you to Placa de Catalunya in half an hour. Buses run every 15 minutes. If you arrive late at night, you can take a taxi or a bus running every hour 24 hours a day. If you want to get to your destination on time avoiding traffic jams, it is better to take a commuter train.
