Essentially, each terminal functions as its own airport with its own parking
facilities, restaurants, shops, baggage claims, custom clearance and ticketing
counters. Of the four terminals, terminal 2W serves most of the international
airlines such a Korean Air, Lufthansa, and British Airways while terminal 4E is
shared by Delta Airlines, Aeromexico and Atlantic Southeast Airlines
