Berlin Brandenburg Airport is an international airport that is under construction. The airport is on the border of Brandenburg in the southeast of Berlin, Germany. The airport was planned to begin offering service in 2012 but it couldn’t be put into service because of technical and financial problems. Berlin Brandenburg Airport will take the place of Tegel Airport which organizes flights to important cities of the world. It is planned that Tegel Airport will be closed when the airport will become fully operational. The airport is planned to be put into service in the coming years. It is thought that Berlin Brandenburg Airport, which will welcome approximately 34 million passengers per year, will be one of the busiest airports of Europe in terms of air traffic.
