London Heathrow Terminal 4 - Design

Design

The terminal was initially designed as a facility for short-haul 'point-to-point' traffic, to compensate for its relatively long distance from the airport's central terminal area (CTA). The layout of the terminal, with passenger boarding gates very close to the check-in and security halls, was designed to facilitate rapid movement of passengers through the building (a requirement for short-haul, business-focused flights). Upon opening, it boasted other innovations including the complete segregation of arriving and departing passengers and a departure concourse over a third of a mile long.

Lord King, then Chairman of British Airways, demanded that Terminal 4 be solely for the use of British Airways in order to fulfill the airline's ambition of hosting all its flights in one terminal (an ambition that has still not been realised even with the opening of Terminal 5 in 2008). A similar demand was made on the North Terminal at Gatwick.

Thus Terminal 4's distance from the CTA and design were ill-suited for British Airways' long-haul operations and could be seen as a contributor to the airline's dire operational performance, particularly in the years up to Terminal 5's opening in 2008. For example, passengers had to transfer between Terminal 4 and the CTA by bus rather than by a short moving walkway (as between Terminals 1 and 3 for example) and once inside Terminal 4, the gate areas are not large enough for the 400+ passengers waiting to board the waiting 747s. Passengers' baggage also had to make the trip by van, sometimes resulting in the luggage being mislaid, although this problem was somewhat alleviated in the late 1990s by the construction of an automated transfer tunnel between the CTA and Terminal 4.
