If Katy makes “Walking On Air” a single, it's video needs to be v aesthetic-y like “This Is How We Do” was, but more in an 80s/90s pop culture way. A video with her paying tribute to the most iconic music videos of the 80s and 90s ("Vogue", "Physical", "Girls Just Wanna Have Fun", "Rhythm Nation"/"Scream", "Wannabe", "Nothing Compares 2 U", "...Baby One More Time", etc.) would be AMAZING.
