Same with Legion, before patch 7.2, you couldn't fly in the Broken Isles, so about a year into Legion before you could fly there.
So in a sense you do lose flying sort of. You had flight in Legion for a year or so, then come the new BfA expansion, you move there, level up, and play there most of the time, and you can't fly at all, having to wait a year for patch 8.2 that then allows you to grind away at unlocking flight.
And this Summer Shadowlands will come out, and no flying there for awhile, and you will spend most your characters time in the new Shadowlands zones, but stuck to ground mounts until patch 9.2
