Exactly. Heathrow is oversubscribed, while Stansted struggles for business.
The customers want more capacity at Heathrow area, not east or northeast of
London.

No, they want extra capacity at the main London airport (with lots of
airlines and passengers) which happens to be Heathrow. If Heathrow closed,
it wouldn't be any more.

It's a self fulfilling prophecy, not an overriding desire to visit Slough
on holiday.

Businesses (including company head offices, caterers, hotels, air freight
companies, airline offices, people who need to travel a lot, etc) have
located around Heathrow, and they want the main London hub to remain in the
area. It also has much better transport links than other London airports.
