Me too. I do a couple more quests and it takes me 70 minutes on epic flyers (5 more if I have to farm no rest for the wicked items).

To be precise I do:

5 Tournament quests (chillmaw, the 2 at the citadel and the 2 to kill scourges in icecrown).
Skybreaker: Slaves to Saronite, No rest for the Wicked, Drag and Drop, Neutralizing the Plague, the kill Vrykul one and the two from the gnome downstairs.
Icecrown center: Assault by ground, the jumping robot one, and the first on the pillar.
Ebon Blade: Viles like fire, Shoot Em Up, the one you have to plant banners, the kill 10 gripphon one and the rise ghouls from corpses ones.

Total: 21 quests in about 70 minutes.
