I agree with everybosy else here. Fusion is the only medium term feasible propulsion method that would provide enough energy for space travel, albeit not interstellar travel. If we manage to harness it and make spacecrafts capable of travelling with the solar system to harvest its mineral and gazeous resources, it'll be a good start. The technology can evolve from there once there is a commercial incentive.
Everything other form of space propulsion out there is still highly theoretical, and most of them require amounts of energy we can hardly comprehend, let alone create...
Though it would be cool to see some sort of giant energy capacitor which, once charged, would provide enough energy to locally distort space and time in such a way that it would bring you to another point in space instantly, provided it is at all possible to cohenrently manage that distortion.
I'll do my own airline. With Blackjack. And hookers. In fact, forget the airline.
