Problem is Hinata is NOT Neji.
Hmmm, must be why Hiashi considered her strong enough to fight side by side Neji and protect him (which we saw).
She couldn't even perform 64 trigrams until the end of the manga.
Implying that's a bad thing when that tech is hella hard to pull off. Mukai, who roflstomped Anbu Itachi and Prime Shisui tag teaming him in taijutsu, was only good enough to pull of 16 Palms.
Hinata > Mukai > Itachi + Shisui
Hinata is another story. This Hamura Chakra thing, aside giving it to Naruto what else has HINATA done with it?
The fact that she gave it to Naruto alone is proof that it was significant.
Hinata used her that Chakra to reheal Naruto allowing him to reeneter 100% KCM right after having so much of his Chakra drained that he fell on his knees, a worse case than this, where at least Naruto was still able to stand. so yes, Hinata's chakra saw a massive leap in quantity.

So that means the amount of Chakra is close to 100% KCM, which is at the very least above the Bijuu Cloak she got in the war, meaning she is easily replicating that Air Palm feat, since more Chakra means more power and speed.
Also remember that Rikudo Chakra is more potent than Bijuu Chakra. So both in amount and quality, the Chakra Hinata got is better than the Bijuu Cloak she got.
And she used it to fly at the end of the movie.
