One of the advantages is that Barcelona Airport is close to the city center, approximately 14 kilometers. Specifically, it is located in the town of El Prat de Llobregat, hence the name of the airport. El Prat airport is the second largest in the country, after Adolfo Suarez Madrid- Barajas airport. Passenger traffic in 2015 was more than 39 million passengers and is among the top 30 busiest airports in the world. The airport connects with the United States, Colombia, Argentina, Brazil, North Africa, Middle East, Southeast Asia and Europe.
There are several options of transportation from the airport to around Barcelona: rental cars, taxis, buses, subway (L9) or train.
Vueling airline is the main base of operations at the airport. The busiest route of Barcelona is the ""Air Bridge"" (Airlift or Puente Aéreo in Spanish) connecting Barcelona and Madrid and is the world's most frequented Air Bridge. Currently there are three airlines that operate constantly throughout the year with direct flights: Iberia, Air Europa and Vueling. The companies with more frequent flights are Vueling (about 10 daily) and Iberia (about 12 daily).
The arrival of the high speed train ( AVE ) has reduced the number of daily flights between Barcelona and Madrid but the connection by air between this two cities is still the most commonly used.
Leaving aside the many improvements that El Prat airport has had in recent years, there are still plans for the future. Besides the two existing terminals (T1 and T2 ) is planning to build an additional space called T1 T1 (Terminal Satellite). This terminal will have the capacity to accommodate 25 million passengers a year but for now, the project is stopped because the two existing terminals already cover existing demand for flights.
