Well I wouldn't classify it as a mystery. Well for one, Naruto and his team were conventionally using Sai's bird to travel the long distances. I don't think it would look normal if Naruto was the only one NOT using Sai's animated creations as a leverage towards their goal. I mean a big point in that flight was to showcase Naruto without his powers yet (as they saved KCM until the very end of the movie), not to mention him and Hinata were getting cozy up in the air lol.

It was explained they could breathe because the past Otutsuki clan members built technology that allowed them to do so. Toneri's castle was a big part of it too.

Lastly, no that would not really make sense. Naruto was shown the ability to fly perfectly clear in the movie, because the rest of his teammates and Toneri (before Chakra mode), when they jumped, they fell down. When KCM/Toneri fought, they hovered swaying in the space. Gravity pulls them down, simple logic right? Moving on towards their fight, at 3:11 in the link I posted above, Naruto hovers in the air and creates a large group of clones. Which then press of off nothing and accelerate towards Toneri with a velocity. That is a clear indication of flight, as when Naruto pushed off of the empty space, a gust of white matter appeared beneath his feet.

Nice reply and good questions :)
