Sky News has reported that Global Infrastructure Partners (GIP) and other investors could be potentially interested in buying Aberdeen airport from Heathrow Airport Holdings Ltd. (HAH). GIP currently owns Gatwick, London City and Edinburgh airports. According to the source, Heathrow airport accounts for more than 95% of its parent company's annual profits, which would make the sale of the other regional assets "inevitable" within the next three years. Heathrow Airport Holdings Ltd. (HAH) is understood to be mulling a plan to offload Aberdeen, Glasgow and Southampton airports following several unsolicited approaches from prospective buyers in order to focus on the London hub. Manchester Airports Group, which owns Stansted, would also be a likely bidder for some of the Heathrow-owned airports. Other sources said that Ferrovial, owner of 25 % of Heathrow Airport Holdings Ltd. (HAH), is likely to be interested in acquiring one or more of Aberdeen, Glasgow or Southampton airports through a separate vehicle.
