This listing includes the world's largest airport, construction and investment groups with significant business links and foreign airport holdings beyond their national boundaries

This year has seen a raft of activity in the airport ownership sector, including a number of airports changing hands, the shelving of plans in October to privatise Amsterdam Schiphol, and signs of international ­ambitions from Dubai Aerospace Enterprise's airports division.

In May, BAA completed the sale of its near-75% stake in Budapest Ferihegy Airport to Germany's Hochtief AirPort. BAA acquired the 75% minus one share stake in the Hungarian airport in late 2005, but began selling off its interests in overseas airports shortly after it was taken over by Spanish infrastructure firm, Ferrovial. Hochtief acquired the stake for €1.9 billion ($2.7 billion) as part of a consortium which also includes Canada's Caisse de Depot et Placement du Quebec and Singapore's GIC Special Investments.

In New Zealand, Auckland International Airport became a takeover target, attracting bids from Dubai's DAE and Canada's CCP Investment Board. DAE in July offered to purchase a 51-60% stake in Auckland for about NZ$2.6 billion ($2 billion), but later withdrew its offer following political opposition in New Zealand. In October, Auckland ended talks with CCP, which had proposed creating a newly listed airport company that would have been up to 61%-owned by existing shareholders. DAE's bid for Auckland demonstrated the company's intention to establish a foothold in the airports market. It has said it is looking to own and/or manage airports around the world, with India a possible target.

In Europe, long-running plans to privatise Schiphol were sunk when the Dutch government decided against a flotation.
