What does Top 1% mentioned by ATC refer to? I have watched Live ATC tons of time. But I still don't know which airline is called "Top 1%". Ex: Delta 81 right Bravo right Kilo give way to company A380 and follow the Top 1%".

Just wanna know what "Top 1%" means. Or that is only for JFK?
I'm guessing you're referring to a clip such as this one. JFK ground is just being a bit informal and fun (as you can tell from the rest of the clip) with their instructions. Although it isn't mentioned, the controller is probably referring to a business jet flight, such as ExecJet.

The "top 1%" refers to a ranking based on income, specifically those not in the lower 99%. The controller is basically telling them to follow the rich people in their fancy private jet. JustSid found another video where the controller explains it as "someone richer than both you and me."
