Huh?
Pink Love Rocket has never had anything to do with 310 flight speed. The Violet Protodrake, which you got for completeing the full set of yearly event achievements awarded you 310 flight if you didnt have it already, and I think (not 100% sure) that earning either of the ICC 10 / 25 Glory achieves for the Frostwyrm mounts would give it as well. Blizzard would NEVER have tied something that granted 310 flight to a 100% completely random drop. You always had to earn it.

Would really love to see that screenie, + an armory link, + a verifiably date stamp that proves the mount dropped anytime before february of this year.
Of course, it is not even remotely possibly the person you saw riding the Galleon mount was actually riding http://ptr.wowhead.com/item=89682 instead.
