We’ve recapped all improvements coming to Riding/Flying in Patch 10.1.5.
You won’t need to visit riding trainers anymore in Patch 10.1.5. Just like spells, Riding/Flying is now learned automatically upon reaching certain levels and is completely free.
You will learn Apprentice Riding at Level 10.
You will learn Journeyman Riding at Level 20.
You will learn Expert Riding at Level 30 and receive the Time to Fly Quest that awards faction-specific mounts.
Alliance players will receive Harbor Gryphon.
Horde players will receive Reins of the Scarlet Pterrordax.
If you are at max-level, you will only need to visit Dazar’alor or Boralus for the quest to pop up.
Finally, at Level 40, you will unlock Master Riding (310% flying).
