The Compass Centre, the head office of Heathrow Airport Holdings
The head office of Heathrow Airport Holdings (formerly BAA Limited) is located in the Compass Centre by Heathrow's northern runway, a building that previously served as a British Airways flight crew centre. The World Business Centre Heathrow consists of buildings one and two. 1 World Business Centre houses offices of Heathrow Airport Holdings, Heathrow Airport itself, and Scandinavian Airlines. International Airlines Group has its head office in 2 World Business Centre.
At one time the British Airways head office was located within Heathrow Airport at Speedbird House before the completion of Waterside, the current BA head office in Harmondsworth, in June 1998.
To the north of the airfield lies the Northern Perimeter Road, along which most of Heathrow's car rental agencies are based, and Bath Road, which runs parallel to it, but outside the airport campus – this is nicknamed by locals as "The Strip" owing to its continuous line of airport hotels.
