Burning Crusade introduced flying mounts for both Horde and Alliance players. Once a player reaches level 70, s/he can purchase a flying mount in Shadowmoon Valley. Players must have previously purchased the riding skills for both the level 40 and the level 60 mounts. (It is not necessary to purchase the mount itself to upgrade the skill.)

The first flying mount available to players increases speed only by 60% (less than the level 60 ground mount). In addition to the mount, players must purchase the next rank of the Riding skill. There is a second-tier flying mount, which requires the corresponding (fourth) rank of the skill.

Druids can obtain a flight form when they reach level 68. It will have the shape of a storm crow. This form is just as fast as buyable mounts, thus giving the druids a cheap yet comfortable ride through Outland. The Flight Form is purchased like a skill from a Druid trainer and the 225 Riding Skill is obtained for free. The Epic Flight Form, introduced in Patch 2.1, increases flight speed by 280% but will require the player to purchase the 300 Riding skill in order to use it.

The 2.1 patch to World of Warcraft introduced several new 300 riding skill flying mounts usable by members of either factions. These mounts enable players to travel with a 280% speed increase in the air or a 100% speed increase on land. They can be acquired by completing long quest lines involving repeatable quests to increase repuation. These mounts can only be used in the Outlands.

Unique Mounts

Phoenix Mount

The world’s first Phoenix mount belongs to Ezra Chatterton, the young man who recently went to Blizzard’s offices with the Make-A-Wish foundation.
On May 31, 2007, the guild Method on Sylvanas-EU saw the world first drop of this item when they successfully brought down Kael’thas, making it the second Phoenix mount in-game, next to Ezra’s.
On August 8, 2007, The Phoenix mount dropped for the guild Legions, on Lightbringer-US.
Swift Nether Drake

Also known as the Armored Netherdrake, this mount is a 310% speed seasonal arena reward awarded to all teams who finish in the top 0.5 percentile of their arena bracket. Depending on the battlegroup, this is widely considered to be the most prestigious and hardest mount to acquire.
