It was discovered on the PTR before Blizzard confirmed it, but it's there anyway: players will be able to learn Cold Weather Flying at level 68 in World of Warcraft.
More specifically, players can buy a heirloom item with a current level 80, and pass it on to an alt, allowing that alt to learn Cold Weather Flying at 68 instead of having to wait until 77.
Says Zarhym:
Just to confirm, Tome of Cold Weather Flight is actually a new heirloom item planned to go into patch 3.2. At level 80 players can buy this heirloom item from the Cold Weather Flying Trainer in Dalaran for 1,000 gold and send it to an alt of the same realm, faction and account. The tome can be used to learn Cold Weather Flying at level 68, consuming the tome in the process.
Please note this feature is not yet in the newest version of the public test realm patch notes updated today. The item and its functionality are subject to change during the testing process.
So Cold Weather Flying still won't be at a discount, but at least you can start flying in Northrend when you get there, instead of when you're almost done with the place. Especially useful if you're using the experience boost heirloom items on your alts as well.
