1. Well, portal creation is kinda very complex and advanced ability as it seems, it consumes a lot of chakra too and has some unique drawbacks for the user (i.e. Sasuke losing access to the MS and Rinnegan losing its Tomoe). At the same time, flight seems to be neither complex nor chakra-draining, as it was demonstrated by Naruto in his SPSM, so it should be accessible from the very beginning if there was any.

2. I think this point is somewhat cleared after the look on the Databook.

Also, I should note that we're drifting from the actual topic of this threat, slowly but surely.
