The air and maritime transport markets in Poland are largely well developed. Poland has a number of international airports, the largest of which is Warsaw Chopin Airport, the primary global hub for LOT Polish Airlines. It was established in 1928 from a merger of Aerolloyd (1922) and Aero (1925). Other major airports with international connections include John Paul II International Airport Kraków–Balice, Copernicus Airport Wrocław, Gdańsk Lech Wałęsa Airport. Poland has begun preparations for a construction that can handle 100 million passengers of the Central Communication Port.
