I am a non-gifted person in the air. Been skiing for a long time, sucked at airs back when 'threes' were called helicopters. Lately, I have had a lot more success by experimenting on transition jumps in the terrain parks. Crg speaks the truth with how you are set up at the point of departure, particularly with punching your hands in the direction of travel, and preferably toward where you want to land.
I have also found that for a klutz like me, I have a little mantra (no, not a stubby version of the Volkl) that keeps me focused while I am in the air. While keeping my hands forward and slightly down, I extend my legs at the takeoff (I want air, may as well use my legs to give me more of it), retract my legs right after that (keep all my parts compact and stable), look with my eyes for a landing spot, and extend my legs again to absorb the touchdown (which, on a carefully prepared transition jump, is the softest landing there is...).
Extend/Retract/Look/Extend... it all happens quickly at first, but after a while, it seems like an eternity and you start thinking what else you can do (like a three) while you are hanging out above terra firma. That is oversimplified, since something like a three takes intent before you take off, but you'll see what I mean when you have a go at it.
Good luck, weightlessness is just as fun as The Perfect Turn.
