Well in the ToH when Natsu literally grabbed Jellal and pushed him through the floor, he and Jellal went through quite a few floors before Jellal broke away and flew back up with Meteor, and yes, while neither of them were ground level, if the rock Natsu had jumped up to before the big jump was at ground level it'd show Natsu being able to close the distance at a very fast pace, a pace which Jellal was unable to even react to until after Natsu had made contact with him and they'd gone back past the floor they were fighting on and even further into the air, where Jellal then kicked Natsu back and continued to go higher. I do get your point that Natsu can't get a boose like the ground while in the air, but what the ToH did show us was Natsu still close a fair distance in the ToH to be able to catch Jellal and hit him before he could even react.Yea, he can jump off flat ground to quite a height. The reason why I bring up those rock support things is due to the ALTITUDE. Now why altitude? Because Natsu needs at least a good height which is reachable to Jellal. So if Natsu can catch up to Jellal at the first few seconds of his take off, this will be a much tougher fight. But Jellal is not that dumb. He could fly in any direction and easily evade Natsu. But when he is doing so, he is flying much higher. My point of argument is that those rocks were never ground level so Natsu wouldn't have even reached Jellal if he took off from the ground and needed those rocks to gain enough altitude until he blitzed Jellal. I am all for Natsu being faster than Jellal but he does not have equal maneuvering while airborne like Jellal. His propelling tho kinda amazed me but again he only reaches his opponent when he has a perfect altitude/height required.
Its kinda fun debating with you. These are all my opinions and I easily see Jellal getting airborne (unless there is a wild possibility that Natsu will catch up to him WITHOUT environmental advantage)
Hope we have fun discussing other points. This has been the most evenly matched fight other than Jellal vs Laxus.
Edit;-Sorry I forgot to address you Natsu moving in air point. I agree that Natsu can do it but Jellal's level is much better and hence, I stated that his maneuvering in air is much higher than Natsu's. Plus, its game over once Jellal gets above a certain height like I stated.
Also while in the air, I should make the point that in this fight, Natsu doesn't need to get right up close to Jellal in the air to hit him, as a roar or Flame Dragon King Roar, especially the latter, have a large AoE so Jellal would still get caught up in it if Natsu fired it off and if Natsu did it in FDKM, imagine just how large the AoE would be, and then think about how powerful it would be. If its at the same kind of power as the Demolition Fist, then Natsu could end the fight there with the roar.

. What I mean is if Natsu uses one of his mightier spells and Jellal manages to dodge it and he definetley will be able to do that sometimes cause of his speed, he has an opportunity to strike back!
. As I stated before, Jellal has so many 'building blocks' for his victory. Natsu has raw power. IMO, Jellal takes this but opinions always differ.
