The city of Brussels is served by two airports: South Charleroi (CRL) and Brussels Airport (BRU). Brussels Airport is located northeast of Brussels and transports a large number of passengers every year. The international airport uses only one terminal building with different levels separating the various facilities. The railway station is positioned at Level 1, the buses and taxis standpoints at Level 0, while arrivals and departures are situated at Level 2 and Level 3 respectively. South Charleroi Airport has two terminals: 1 and 2. There are over four daily direct flights from Brussels to Barcelona and some connecting flights via Frankfurt, Amsterdam, Zurich and Geneva.
