The Standard also noted the XRL is $67B. The third runway will be almost twice that

For one more comparison of size, Festival Walk's only $22B

Although I still think the 3rd runway will have greater economic benefit than the XRL (I don't think of the XRL as anything but a white elephant, even as a (former) frequent PRC business traveller), it does make me think whether we can afford it - it can be useful but just too bloody unaffordable.
