The Airlines are being gouged for the privatised airport incompetence. As the fuel wasted does not affect the airports bottom line they don't see any point in building new runways. Would the fuel wasted each year pay for a new runway, I think so and maybe even a third. The Government needs to step in , use government bonds to build all the new runways and at the same time take 50% ownership of each Airport back .
Why did our Government sell so many monopoly assets , licences to print money . Australia is really a financial disappointment and is heading toward 3rd world status.
