Celestial Steed Question

Q u o t e:
Once activated, this World of Warcraft in-game mount code applies to all present and future characters on a single World of Warcraft license.

The Celestial Steed will work similarly to other pets purchased from the Blizzard Store. While the pet will be awarded to all characters on the redeeming account, it's not technically Bind on Account. If a character with the Celestial Steed transfers off the redeeming account, it will lose the Celestial Steed mount spell.
