Incheon International Airport's new terminal building is scheduled for completion by the end of September.
After a roughly twelve week-long trial period, the new terminal will be open to the public from January next year, just in time for the 2018 Pyeongchang Winter Olympics, which kick off the following month.
Four airlines -- Korean Air, Delta Air Lines, Air France and KLM Royal Dutch Airlines -- will move into the new terminal.
The terminal, which has five stories above ground and two underground levels, will be equipped with 22 state-of-the-art full-body scanners, capable of detecting dangerous materials that cannot be picked up by metal detectors.
After going through security and passport control, passengers can enjoy some tax-free shopping at various duty-free shops in the new terminal.
The Incheon International Airport Corporation says the new terminal will be connected to the subway line and have its own bus stops for passengers' convenience.
Once open, it's estimated Incheon International Airport will handle some 72 million passengers a year up from the current 54 million.
