I don't recall it ever being on the show, Anks, no.
When I introduced this element into into one of my own fanfic - it was one of my nfic vignette romps, but can't remember the title - it just seemed natural to me that someone who could fly so easiliy under his own steam would hate the confining elements of flying by plane. I never thought Clark was afraid of flying by plane. Just that it would be restrictive and boring for him.
I don't remember at the point of writing that one having read anything else with this element, but I'm certain there must have been something out there somewhere by that point, fanfic already being well established when I wrote my first LNC story. So I've no idea who came up with it originally.
