How to Unlock Flying in Shadowlands

Hey Guys, i logged into World of Warcraft Retail since launch, my first question was how do i fly like everyone else? a few whisper got me a few vague answers, "do the story" well i did the newest story which gave me wonderful loot but no flying. i was doing the story out of order from newest to oldest trying to unlock flying. if i had only known what i know now. The last sigil quest and your covenant campaign were the only parts i needed to fly.
