There are very few spots, wher you can cross from server to server (e.g. Blasted Lands to Outland, EPL to Ghostlands etc etc). If you had the option to fly west from Kalimdor, to arrive in EK, then too much of the server load, would be dedicated to keeping track of when people cross from server to server.
You'd also have to expande the maps with nothing but water, only to accommodate this change, which would be irrellevant for the vast majority of players..
