I've been questing with my wife for much of her journey through Azeroth, Outlands, and Azeroth. I was the one to push for ground epic mounts as soon as we hit 60 so that we could go fast. (It was one of my alts that leveled with her through 70, but from 70-80 it has been my main, Leiandra.) Now that she hit 77, the difference in waiting with her slow mount and my fast mount was just unbearable. Now, I'm not one to have a lot of money. I'd much rather focus on other things besides saving my in-game money. So, 5,000g is still kind of a lot of money to me.
But it was slowing down our progress, and I found I had to wait a lot. So, I gave her the money for the fast mount. Heck, I still have other 70's that don't even have epic flying. But, I think it was the right decision. So, the question here is twofold: (1) How many toons do you have with epic flying skill? (2) Have you ever bought epic flying skill for somebody else?
