The Zevhra was available from August 2008 (WotLK launched in Nov 2008) till April 27 2010.

Kind of moot when it comes to the mount now that we’re a few months away from cata, but it sure would have been nice to have a 2 person flyer, like we had originally in WotLK. Unfortunately, the devs instead decided to add unclassic stuff to the game, like Titan Rune Dungeons.
