How do I fly?

[Punchyghale]

I bought a Gryphon and learned riding, but it says you cant use that no matter where I go. I googled it and it said there was an NPC in SW beside the Flight Master that would let me fly but I cant find it.

On WoTLK expansions, you start flying in Outland, getting level 60 and obtaining the riding skill. This locks your flight to Outland zones only. After that, you can unlock flying in Northerend, by going to dalaran at lvl 77 and purchasing the Cold Weather Flight ability. Though if you have a level capped character, you can buy a book that will teach the Cold Weather Flight thing at level 68, and you can mail it to your own lower level characters.

You can only fly in Outland and Northerend, not in azeroth like in the further expansions.
