BAA
BAA plc was bought in 2006 by a consortium led by Ferrovial, a Spanish firm specialising in the design, construction, financing, operation and maintenance of transport, urban and services infrastructure. In March 2009, the company was required to sell Gatwick and Stansted airports, and over the following years sold all its airports other than Heathrow. The company was renamed Heathrow Airport Holdings in 2012 to reflect its main business.
