Heathrow was built haphazardly as traffic increased since its opening in 1946, with a capacity to handle 45 million passengers at its 4 terminals it was congested and handled 68 million annually. The building of Terminal 5 will ease congestion and increase capacity by 45% making a big difference for British Airways which will operate out of T5 and a big difference in baggage handling ( a million bags weren't ready for passengers at destination in 2006), in the lounges and lounge environments for waiting passengers 2500 at a time) ., and after an annex is built by 2010 passengers will not have to be taken by bus to waiting planes. other airports like Schipol with 4 runways compared to Heathrow's 2 and built with a better layout and plan, and airports in Asia of Singapore Airlines and in the Middle East at Doha are upgrading so BA will only be doing what places are doing. Because the terminal hangups have been costly for British Airways leading to a shrinking of about 20% of its flight network, as it concentrated more on upscale customers, and lost passengers to more efficient airlines., ithe cost will likely be paid off quickly for BA. Demand. is so high at Heathrow that a pair of takeoff and landing spots can cost as much as $50 million and would be going up as Star Alliance and Skyteam member airlines move ito BA's old facilities. Considering the losses from th inefficient setup at the old terminal BA's estimate that T5 savings would cover its cost of 330 million pounds ($660 million) to equip the new building in in the next 10 years may even be understated. Of this 62 million pounds was spent on the new lounges. BA leases the T5 Terminal from Heathrow's BAA owned by Spain's Ferrovial SA, which spent $4.3 billion to build T5. ...
