Airports in Poland are currently experiencing very rapid growth, as a result of the fastest increase in air traffic anywhere in the world. However, Polish airports still suffer from underinvestment, inadequate infrastructure and limited capacity. The sector is expecting investments worth an estimated €1.2bn between 2007 and 2013, with credible plans to establish several new civil airports in Poland. The Polish airport industry enjoys the very good prospects. In 2006 more than 15.3 million travellers visited Polish airports, over one third more than in 2005. In the same period, average airport passenger traffic in Europe grew by some 7%.
