| By Continent |
A flight path (often abbreviated an FP) is the primary means of zone-to-zone travel on Azeroth. They are a transportation link between two fixed geographical points via fixed paths on faction-exclusive aerial mounts. The Alliance utilizes both the gryphons of the Hinterlands and the hippogryphs of Kalimdor for transportation, while the Horde uses Kalimdor's wyverns and Lordaeron's massive vampire bats.
A flight point is manned by a single level 65 elite NPC, a flight master. A flight path must first be "discovered" by visiting an area's flight master, who will give you access to their flight point's route. If a flight master has a flight path to teach you, a green 
will appear above his or her head, and the flight master will appear as a on your mini-map. Once you learn a flight path, it will be offered as route by the flight master. If you've learned all consecutive flight paths in between, you can choose a far-off destination in the flight map window and you'll automatically fly there -- the routes will be chained together.
The cost of flights is reduced by 5-20% due to the faction discount based on your reputation with the flight master's faction.
Flight Paths are only slightly faster than a 280% Flying Mount. Flight Paths usually take turns that do not need to be taken to reach its destination. By using a swift flying mount, you can most likely beat a flight path to a destination. Epic Flying Mounts are said to travel only 10% slower than a flight path with a Riding Crop.
If Flight Masters are attacked by members of the opposing faction, Flight masters will spawn a pair of level 65 elite adds to defend themselves (Enraged Wyverns or Enraged Felbats for Horde flight masters, Enraged Hippogryphs or Enraged Gryphons for Alliance). Flight masters will not attack players from the opposing faction just for being approached. You must attack a flight master in order for it to aggro.
It is possible to stop your flight short after you have begun a flight by logging out and logging back in. This will cause your character to end his/her flight at the next flight point.
New Characters
New characters in Azeroth automatically know their capital's flight path.
For example, if you are an orc or a troll and you visit the Crossroads before visiting Orgrimmar, talking to the Crossroads flight master will show that you can fly to Orgrimmar even though you haven't visited there yet.
