It's not just the runway utilisation, we are now having to put departures 3 mins apart because of LTMA saturation.
They need to redesign the whole of the airspace to make the airport reach it's full potential. And that is years away.

P.S> Can we have an ILS glidepath that works in the heavy rain please..... and some control over the shipping that blocked the approach yesterday (again) and resulted in holding at SPEAR and go-arounds.
