I don't really see the point of an express train to the airport. Who's in a rush to get to the airport where you already have to get there very early anyway and do a lot of waiting?
In some parts of the world, a short flight is supposedly just as convenient as hopping on the bus or train. Hop over to the next city, the next state.
At least where I live, a two hour flight becomes a six to seven hour ordeal, with ninety minutes for security etc, ninety for travel to and from each airport, ultimately turning what is really not that long a flight into a full day of traveling.
I understand the dream of getting to & from the airport in a speedy timeframe.
