Terminal 3
Terminal 3 will be re-developed and the forecourt will be modernised by the end of 2007. This will significantly improve the passenger experience, reduce traffic congestion, develop better pedestrian routes and improve security in the area in front of the terminal. We also have plans for a £1 billion upgrade of the rest of the terminal over the next ten years.

Terminal 4
Heathrow's youngest terminal, Terminal 4, opened in 1986. Although the building itself is in good structural condition it is in need of extensive refurbishment. After the opening of Terminal 5, BAA will embark on a major upgrade of the existing Terminal 4 facilities. We will look to increase the amount of natural light entering the building, improve the facilities for check-in and build modern departure lounges.
