I will show you how to get to Icecrown without a flying mount.
This is for whoever wants to grind on the mobs found in icecrown early, or just want to explore it.
First, you need to be in dalaran. Have a friend mage port you there, this is the easiest part.
Second, unless you are a mage, you will need a Noggenfogger Elixir - Item - World of Warcraft
You need this item to get the effect to fall slowly.
Here are pics to show you step by step.
This is where you need to be in dalaran
Drink the Noggenfogger until you get the slow fall effect. Then jump.
This is where you will be landing
