Alt skip help!

I was leveling an alt with my friend, so I didn’t skip the story now he isn’t playing and I don’t want to have to finish the story. my question is do I have to finish it? or can I just move on to the campaign that I have for “Dragonflight”? The whole time I’ve been doing the story hasn’t been part of the campaign that I have active. please help lol

I am assuming you were leveling outside of the Dragon Isles and are now of a level you can go there with the alt via the portal in the faction capital if the alt is lvl 60 if you have done the DF campaign, your alt should be able to jump right in as long as you have gotten Dragonriding you should be able to activate Dragonriding on your alt
