It is one of this movie mysteries :) Or we could assume it is because they are on the Moon, lower gravity and so on (of course here comes question - how they could breathe :D).

But more likely it is to make this fight more effective, Naruto didn't show the ability to fly earlier. If he could fly why he needed clones and Sai's bird when Toneri took Hinata after Naruto's confession?
