It's not just about CO2 levels is it?
Even if you dismiss the fact that the airline industry "only" causes 3-6% of global carbon dioxide emissions, there are a raft of other arguments against this development - noise and ground pollution in West London, safety risks, government corruption, flawed economics, etc.
In 2020, people are still going to be able to fly and won't miss out on the chance to see places like Machu Picchu, or any other overcrowded tourist destination for that matter. They will, it's just going to get increasingly expensive as fuel costs spiral again, so 'plebs' will be priced out anyway.
