Mr. Kenny Jacobs:

It is less about infrastructure. We are not incentivising them with a discount on fuel; we are giving a discount on landing charges to newer aircraft, which are more fuel efficient, more CO2 efficient and have higher load factors and newer engines. They are also better from a noise point of view. That is the direction of travel for the airlines, which are replacing their older aircraft with newer aircraft. I think our discount scheme is helping them on that journey, but that is definitely what all airlines are doing.
