Until 2008 it was used mainly by British Airways. It became the Heathrow base for airlines of the SkyTeam airline alliance after British Airways vacated Terminal 4 on 29 October 2009 and moved to Terminal 5.OverviewTerminal designThe 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 . 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 . Upon opening, it boasted other innovations including the complete segregation of arriving and departing passengers and a departure concourse over 1/3mi long.
