Replacing the cramped and outdated Doha International Airport which suffers from limited space and a single runway, the new facility will gradually be expanded as more phases of construction are worked on.
When it opens in April, 12 international airlines will transfer to the new airport.
Qatar Airways will transfer its entire operation to the new Doha airport in the second half of 2013 once extra terminal facilities such as lounges have been completed.
Hamad International Airport has two parallel runways, and a central terminal with various concourses. It will eventually have a capacity for 50 million passengers per year.
