The future of airline sites

This video demo of a mocked-up airline website of the future is stunning. A lot of people are focusing on this as a way of airlines to play travel agent, since there are city guides and hotel information, but the essence of what makes this demo great is the simple ease of use of planning air travel. I've gone from round-trip to one-way tickets in searches and lost all my data, having to start over from scratch (in the demo it's a single click to change). The way multi-city searches are built is also slick and way easier. Of all the parts of this demo I think are worth building, I'd say just the basic new flight search being quick and easy would be a game changer for the industry.
