Work has finally begun on a huge new airport for Berlin. Germany’s transport minister took part in a ceremony at the site, some 20 kilometres from the centre of the city. The project was first mooted after reunification in 1990. Berlin Brandenburg International will replace the capital’s other three airports when it opens, if all goes to plan, in 2011. It will have an initial passenger capacity of up to 25 million people per year, possibly rising to around 40 million. But it will not be Germany’s busiest airport – Frankfurt sees more than 52 million passengers a year. Low-cost airlines have complained its size means passengers will have to walk further, increasing turnaround times and putting ticket prices up. They also fear higher operating fees.
