@Dinnerbone I am not familiar with GitHub so I'm not sure if there's an easier way to paste this here, but

/**
* Determines if the Player is allowed to fly via jump key double-tap like in creative mode.
*
* @return True if the player is allowed to fly.
*/
public boolean getAllowFlight();

/**
* Sets if the Player is allowed to fly via jump key double-tap like in creative mode.
*
* @param flight If flight should be allowed.
*/
public void setAllowFlight(boolean flight);

from https://github.com/Bukkit/Bukkit/blob/master/src/main/java/org/bukkit/entity/Player.java has a different definiton of these methods. If you still confirm what you said above (about only being like a permission to fly, not a way to) then I just want you to know the bukkit comments say otherwise.

I'm amazed by the network of way the Bukkit API works seamlessly with the net/minecraft codes btw :)
