[2] The airport is planned to be located approximately 40 kilometres (25 mi) southwest of Warsaw, connected to a new high-speed rail network and controlled-access highway system linking it much of the rest of the country.

[8] The airport's planned site is about 40 km west of Warsaw, next to the village Stanisławów which is part of Gmina Baranów in Grodzisk Mazowiecki County.

The A2 autostrada and railway lines run in the immediate vicinity of the potential construction site, and Wrocław (Expressway S8) and Poznań (National road 92) is nearby.

Before recommending Baranów, the Arup consulting company analyzed a list of potential locations, including: Modlin, Wołomin, Sochaczew, Mszczonów, Babsk, Nowe Miasto nad Pilicą, Grójec and Radom-Sadków.

On 12 May 2005, the Civil Aviation Office signed a contract with the Spanish consortium Ineco-Sener to carry out a feasibility study of the central airport.

[15] Such a study was nevertheless not actually carried out during the next two years, which was interpreted as a sign that the project of a new big central airport was being postponed until an indeterminate future.

[19] Terminal concepts were prepared by six top-name design studios: Foster + Partners, Grimshaw Architects, Chapman Taylor, Zaha Hadid Architects, Benoy, and Pascall+Watson: In October 2024, the design of the estimated PLN 131 billion (£25 billion) airport and transport interchange was finalized by an architectural consortium led by Foster + Partners and Buro Happold.
