I am surprised at the amount of comments in support of this, at least in theory "If the train network was a viable alternative etc etc" on a FF forum. While I don't agree on this either, a better way would be to ban status runs, i'm sure status run aff'ers contribute a fair amount of emissions with "unnecessary business class flights". Personally I don't view the way to achieve things is through banning/ restrictions. Usually there is an economic solution to solve a problem. Without trying to get too political here, generally banning things outright have other consequences.
What I would be in favour of is subsidies or other things to encourage the development of highspeed rail along the east cost of aus. Help the rail to become so good people don't WANT to fly anymore and the market will decide. Like this comment:
I recognise air travel does have a carbon footprint, I purchase the carbon offset for my flights and try and cut back my carbon footprint in other areas where it makes sense, but I'm not really in support of "banning" people purchasing tickets. This will just drive up the costs for the connecting passengers who have to wear the additional operating costs that would be covered by people on a single leg ticket. Or the flight will just cease to exist, meaning someone coming from another sector will have to change modes of transport to get to this destination.
Also this worry's be about the slippery slope argument, yeah this specific circumstance might not have any impact on us aus. But years from now 2.5hr could be stretched to 5hr etc (the article did mention they were aiming for 4 hours). Look its unlikely but I don't like the precedent it has set.
