In a new report published today, the body believes the downsizing of the company, which trades under Heathrow Airport Holdings Ltd, is on course to generate the windfall by 2020.
Writing in The Times, CMA chief executive Alex Chisholm said forcing the airports operator to sell off Gatwick, Stansted and Edinburgh has resulted in a more competitive marketplace, which in turn has fuelled more investment and faster passenger growth.
The CMA also said that the sale had led to a better quality of service at Heathrow. “In a more competitive environment and with the freedom to make their own commercial decisions, UK airports are working harder to attract passengers and airlines,” added Chisholm.
