The problem is not to to just get from point A to B, but to have a good experience doing it. Air travel is getting worse every year. Starting from the airport checks to the long immigration lines (when traveling internationally) and super expensive fares for those "cuddly" seats, it can make holidays more exhausting than work. And if you live an hour from the airport, well good luck!
My idea of a grand future is when we can travel across the globe in less than hour, and pay less than $50 doing it.
