Tony Fernandes certainly does not want this link built. As an outsider with limited knowledge of the current flight capacity, it seems like a fairly obvious and high volume route. The drive is too long and the current train route is a complete joke. I think KL would only benefit from this as SG is a much bigger tourist destination than KL. There are surely many people, myself included, who have seriously looked at adding a side trip to KL to a trip to SG, but decided against it due to the inconvenient logistics of getting there. If I need to deal with 2 airports and a flight, I can reach just about anywhere in SEA in a comparable amount of time, for a comparable amount of money. The very poor will not benefit, but that is true of just about anything. The rising middle class would surely benefit, and it does create jobs.
