This type of topic was brought up back when the xpac came out. They have made it a bit easier but except possibly when 4.0 comes out they aren't going to make it automatic outside of one area. It ain't that difficult to do, this really is just a complaint thread.

As well, by the time you start getting quests requiring flying you should already have/almost have access to it (and already have all the quest giver aerthers.)
