The most important airport in Poland is Warsaw 'Frederic Chopin' International Airport. Warsaw's airport is the main international hub for LOT Polish Airlines. In addition to Warsaw Chopin, Wrocław, Gdańsk, Katowice, Kraków and Poznań all have international airports. In preparation for the Euro 2012 football championships jointly hosted by Poland and Ukraine, a number of airports around the country were renovated and redeveloped. This included the building of new terminals with an increased number of jetways and stands at both Copernicus Airport in Wrocław and Lech Wałęsa Airport in Gdańsk.
