When affecting with Slow Falling 10 (I think any modifier of Slow Falling will do this, but I entered 10) and equipped with Elytra, in Creative mode, when you are starting to glide, you can do a glitchy infinite flight glitch by pressing the jump button which gives you a small amount of lift in the air. Keep in mind that this only happens when all the specifications are followed, and trying to jump constantly might make you creative mode fly.
