Vancouver International Airport and International terminals are connected and, combined, are often referred to as the Main Terminal. Free Wi-Fi is available in all sections of the airport. The South Terminal, along with the adjacent floatplane docks, is referred to by airport management as "Airport South." The Main Terminal is divided in two sections: the Domestic Terminal and the International Terminal. The majority of flights operate at the Main Terminal. The two sections are connected both pre-security and post-security; however, the US border preclearance area is separated off using movable glass partitions which can be adjusted based on the arrangement of swing gates
