Generate text that refutes this claim: Heathrow is full; it must expand  Put simply Heathrow is at the limits of its capacity so there needs to be expansion. Heathrow is already at 99% capacity and running so close to maximum capacity means that any minor problem can result in large delays for passengers. London’s major rivals have four-runway hub airports Paris, Frankfurt, even Madrid [1] this means these cities have much greater capacity as they can take up to 700,000 flights a year compared to Heathrow’s 480,000. [2] Britain does not want to be left behind, crumbling in the dust. These airports therefore clearly have the capacity to take flights that would otherwise be going to Heathrow. Heathrow needs to expand to maintain its competitiveness so that the airport retains its position the most popular place to stop-over in before catching a connecting flight. Colin Matthews, the chief executive of Heathrow (formerly BAA) has argued that Heathrow’s lack of hub capacity currently costs the UK £14billion. [3] Heathrow is in danger of falling behind continental rivals in Frankfurt and Amsterdam.  [1] Leunig, T., ‘A third runway?

It is not as simple as considering that Heathrow is at capacity so everything will go to competitor airports. So far it is simple alarmism to warn of traffic going to European competitors, John Stewart (chairman of HACAN, Heathrow Association for the Control of Aircraft Noise) points out that the airport already has more departure flights each week to key global business centres than its two closest rivals in Paris and Frankfurt combined. [1] Heathrow being at capacity may encourage other forms of transport, for example encouraging passengers to take the train rather than the plane to Edinburgh, Paris, or Brussels. Secondly it is not always simple just to change hub. As a transfer point if moving airport it would be necessary to change dozens of flights to enable the same transfers not just one or two. And finally of course Heathrow’s expansion is not the only way to deal with excess demand at Heathrow, numerous other options have been proposed from the ‘Boris island’ airport, to linking Heathrow and Gatwick by high speed train.
