The walk takes just over 15 minutes at a high pace.

Terminal 3 includes a multi level underground structure, first and business class lounges, restaurants, 180 check-in counters and 2,600 car-parking spaces. The terminal offers more than double the previous retail area of concourse C, by adding about 4,800 m2 (52,000 sq ft) and Concourse B's 10,700 m2 (115,000 sq ft) of shopping facilities.[6]

When completed, Terminal 3 was the largest building in the world by floor space, with over 1,713,000 m2 (18,440,000 sq ft) of space, capable of handling 43 million passengers in a year.[7] That record was overtaken by the New Century Global Center in 2013, but Terminal 3 remains to be the second-largest building in the world by floor space. A large part is located under the taxiway area and is directly connected to Concourse B: the departure and arrival halls in the new structure are 10 m (33 ft) beneath the airport's apron. It has been operational since 14 October 2008, and opened in four phases to avoid collapse of baggage handling and other IT systems
