Top 10 Airports in the World 2018

An airport is an aerodrome with extended facilities, mostly for commercial air transport.[1][2] Airports often have facilities to store and maintain aircraft, and a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off[3] or a helipad,[4] and often includes adjacent utility buildings such as control towers, hangars[5] and terminals. Larger airports may have fixed-base operator services, airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services.

An airport with a helipad for rotorcraft but no runway is called a heliport. An airport for use by seaplanes and amphibious aircraft is called a seaplane base. Such a base typically includes a stretch of open water for takeoffs and landings, and seaplane docks for tying-up.

An international airport has additional facilities for customs and passport control as well as incorporating all of the aforementioned elements above. Such airports rank among the most complex and largest of all built typologies with 15 of the top 50 buildings by floor area being airport terminals.
