Agreed, but isn't O'Hare the busiest airport in the US?

Edit:- It's Atlanta.

Busiest airspace and busiest airport are two different things, technically.

The airspace that combines JFK, LaGuardia, and Newark, is the busiest airspace in the US.

It's a crazy airspace. Add to that Teterboro, 12 miles from NYC and Republic ~20 miles from NYC, along with all the heliports on the Hudson.

I don't envy anyone having to work in that airspace in any capacity.
