Spanish capital, Madrid, is also the country's largest city and an important trading centre. Madrid's airport is officially known as Adolfo Suárez Madrid-Barajas Airport, though most people call it Madrid-Barajas Airport. This is one of the oldest airports in Western Europe and has been operational since 1931.
If you are taking one of the flights from Madrid to Barcelona, you will be pleased to know that the airport is close to the city centre. This airport has four terminals that are all built in a modernist architectural style. In order to alleviate the stress levels of passengers, Terminal 4 was specifically designed to create a calming atmosphere.
