What I thought suss when looking at the video is that his feet were static relative to each other as he moved through the air. This indicated to me that he was actually standing on a glass sheet or some other fixed object when the footage was taken and then it was superimposed over the background. If he was not standing on a fixed object and truly moving through the air, you would expect some independent movement of his feet relative to each other.
Apart from the video I posted debunking his acts, I have seen similar videos exposing the same sort of tricks. It usually boils down to several videos being sewn together to give the impression that, for instance, looks of astonishment are because of what was just shown immediately before, when in fact they may be because of something completely unrelated.
Many of the bystanders are in on the act and the TV studios that produce this stuff are well aware that it is all a fake, but ratings is what they are after. The same goes for the so called psychics like John Andrews (?) where the live footage is severely edited by removing all his false "readings" so that what is shown gives the impression of a hit rate far in excess of random chance. If you look up James Randi on YouTube, you will find lots of stuff where he exposes these types of frauds.
