Running airports is a complex business and Heathrow's owner, BAA, works in partnership with many other organisations to deliver a high-quality service. Hundreds of different businesses and government agencies work at Heathrow, from the largest airline alliances to independent business operators such as taxi drivers. In addition to carrying out our own responsibilities, BAA has to ensure that all these organisations work together seamlessly in the interest of the passenger. Take a look round our interactive airport (requires flash) and see who does what or read on...
