Of course, in our usual obsessive way, we act as if our runways are the only ones in the world and that air traffic to the UK will continue as it is whether or not we do what needs to be done.
Schiphol airport has
6 runways and you can see that they are not stopping.
Schiphol, home base to KLM, attracted 68.4 million travellers, consolidating its lead over Frankfurt and putting it within 1 million of the total at Charles de Gaulle, which is the headquarters of the Dutch carrier’s parent Air France.
When you see what is being said about Heathrow and what is being done to knock Heathrow off it's perch...
London Heathrow remained Europe’s leading airport despite the constraints of only two runways as airlines turned to bigger planes to boost capacity. The U.K. hub isn’t due to get a third strip until 2025 at least.
Amsterdam lifted passenger numbers 7.7 percent in the 12 months, the most among Europe’s top bases, following 9.1 percent growth in 2016. That’s contributed 10.2 million more travellers in just two years, the equivalent of adding an entire airport such as Glasgow’s main hub.
Paris CDG has
4 runways. Orly has
3 runways. If you add Beauvais, which is pretty much like Stansted and Paris has 8 runways. As Gatwick only has one functional runway at any time, London has 6 runways if you count City but City is so small that it can only take very limited aircraft. It's more like Dundee.
You'd have to add Southend to get 6 real runways.
Schiphol has excellent interconnections around the EU and has a large rail hub. Paris also has excellent interconnections and a massive high speed rail hub in Paris, just 45 minutes away. Fly into Paris and you can be in other, harder to get to places, 3-4 hours later.
Paris has the runway capacity of all of London, plus Birmingham and Manchester. It has EU wide interconnection links with other transport, incredible numbers of hotels right on site and continues to grow. Major downsides with Paris are overcrowding, older, poorer terminals and the fact that it takes you a minimum of 10 minutes to taxi to your gate and it is the slowest airport to get off the plane and connect than any other I've ever been to. Oh and the fact that they all speak French, not English doesn't help either.
Heathrow, essentially, is not about how we, in the UK, want to travel. It is about the UK and how the UK is perceived in the world. As we exit the EU, Heathrow remains the largest International hub in the world, the largest transcontinental hub in the world and a prime destination for travellers. Barring a new hub, of the size of Heathrow (which is why I was with Boris on the Thames Estuary), it is Heathrow that has to grow. I'm not opposed to growth in the other airports, but we need to do Heathrow first.
To be honest, if we do see the spaceport in Scotland that we're being promised; it might be better to look much further North for Airport capacity than south in the future. After all Space is the real future and, of course, nobody wants rockets going off in their back yard do they? They're really noisy and pollute like hell.
