There should be an "Unlock Flight Paths" heirloom available for alts if you have every flight path unlocked.

Not that it's a huge inconvenience, but I'd really like to at least have access to all of the Eastern Kingdoms and Kalimdor flightpaths unlocked on a fresh character from the get-go. Boosted characters come with them all already unlocked, so I don't see why this isn't an option.Thoughts?
