The Gulf emirate of Dubai wants to build the world's largest airport, which will be the equivalent of Chicago and London Heathrow airports combined.

The Dubai World Central Airport, at Jebel Ali, aims to handle 120 million passengers a year, Bob Johnson, the chief executive officer of Dubai Aerospace, according to a news published at the Khaleej Times.

He told industry experts at the Dubai Airports and Dubai Duty Free Suppliers Forum on Tuesday that Dubai World Central would be the airport of the future, offering less bureaucracy and inspection procedures for passengers.

"They've (airports) evolved to places where you get on a plane to a place where you and your bags are inspected," Johnson said.

"I think while we can make it safer, we can also make it quicker.

The aim should be from kerbside to planeside in 15 minutes," the company official explained.

The mega airport will be opened in 2009, according to airport officials.
