The new $1.2 billion Concourse D has opened at Dubai International Airport, increasing capacity at the airport from 75 million to 90 million passengers a year.

British Airways’ flight 105 from London was the first to use the new facility, which will eventually be home to more than 70 international airlines. The concourse is linked to the newly renovated Terminal 1 by a dedicated airport train that can transport 300 passengers per trip.

Opening the new concourse, Sheikh Ahmed bin Saeed Al Maktoum, chairman of Dubai Airports, president of the Dubai Civil Aviation Authority, and chairman and CEO of Emirates Group, said: “We continue to invest in the development of top-flight infrastructure to augment service levels for our international airlines and their customers while providing the capacity needed to meet growing demand. Concourse D has been designed with … shorter walking distances, more comfortable seating areas, more choice in lounges, and a world-class retail and F&B offering.”

The formal opening followed months of intensive testing and a successful operational trial involving 2,000 members of the public earlier this month. British Airways and Royal Jordanian were the first two airlines to occupy the new facility, with the remainder phasing in operations over the next several weeks.

Dubai Airports CEO Paul Griffiths said: “Concourse D continues our legacy of providing timely capacity” in line with “our 2016 forecast which projects 85 million passengers will visit Dubai International this year.”

Designed to handle 18 million passengers a year, airside facilities include 21 contact stands, four of which will be able to accommodate Airbus A380 or Boeing 747 aircraft, and 11 remote stands.
