This video doesn't specifically shows / says they can't (or I missed that part). My JP isn't perfect, but I think this page http://awvssao.bn-ent.net/system/active.html mentions the differences between SAO and AW characters general gameplay. SAO characters have Sword Skills, Magic and flight, while AW characters have speed moves (instant dash and super jump), and special abilities with the clear exception of Silver Crow that can fly too.

So to go back to your question, I think it's not that important to show that AW characters can't fly, is it? Since the only expections to that "rule" are Silver Crow (common sense due to canon lore) and Kuroyuki Lotus, which is the point of the trivia, I think?

I've had a talk with ZeHaffen there: http://swordartonline.wikia.com/wiki/Thread:60848, in which I mentionned other characters that can more or less "fly" in their own way, but following his logic of "true flight" (being able to stand, move and fight endlessly while being in air without "jumping"), I only focused on Kuroyuki Lotus.

The others I had mentionned in that talk were Sky Rakers (jetpack style flight, which turns off once the gauge runs out or when fighting), White Cosmos (who's on a "levitating" chair at all times outside the main town), and Chiyuri Bell (who goes on an endless "rocket flight" until she starts a fight or cancels it) who is actually on the video, but Havian didn't try to press "up" due to the AW characters' rule of "not being able to fly".
