Do we need airport expansion?

Sure, expanding our aviation capacity (New sky thinking: The airport debate, 2 November) has many benefits such as tackling delays and congestion within our existing airport infrastructure. But what I fail to grasp is the claim that we need to expand to keep up with our global competitors.

It might just be me but hasn’t the way we conduct global business changed dramatically over the past decade or so? Conference calls and other forms of global communication mean there’s much less reliance on jumping on a plane to travel thousands of miles to go to meetings.

Maybe there’s something I’m missing here? For me, the argument that airport expansion is vital for economic growth seems tenuous.
