SOCAL is the busiest, and it’s *really* busy! Nice bragging rights, but you still have to be a Californian to brag about it, so there’s the downside.

To sum up, California is extremely congested, overcrowded, overrated, underfunded, and most of it lies on the wrong side of the big crack which makes that part of the state perilously close to becoming an island or New Atlantis. Congrats!
Funny, cause I find California beautiful, wealthy, spread out, tasty, underrated and with a massive surplus. Plus, we have the best flying in the world.
I'll bite. Chicago, Atlanta, Denver and Miami. But if you go back far enough I'd bet they all are a combination of former standalone facilities.
Isn't Chicago approach a "quasi-super" TRACON, given that they cover ORD and MDW, plus whatever else?
Back on topic, during my SoCal TRACON tour they did day that it was most likely the last of the Super TRACON facilities to ever be built. Moving forward the FAA is going with a smaller regional approach to the physical facilities both for security and distribute the risk of one jackwaggon compromising the entire system at a consolidated facility.
The Chicago Center thing really made the FAA rethink the consolidation trend. So did likely the Miami Center outage. That said, I also think that there really aren't anymore areas where Super TRACONs make sense. It might make sense to transfer facilities like OXR and CMA to SBA, but a full on Super TRACON doesn't really make sense in other places. Maybe consolidating a few "TRACAB" facilities, like AUS and SAT or something like that, but not much further to go.
Hard to believe NYC isn't the busiest
Not really.
Pretty sure New York. But pure size doesn't tell the whole story. A lot of it is Oceanic stuff. A huge piece of Los Angeles is delegated to Joshua Approach and a lot of LA's sky is Restricted and Warning areas that are almost always hot. You really can't gauge 'busyness' on just overall volume of sky and number of operations
Yeah, people forget that Joshua Approach handles a fair bit; and Mugu handles a busy transient airspace, 3 Deltas, one with lots of high performance military, and one of the busiest G's anywhere.
So True. Three Class C's that either overlap or abut LAX's Class B, another C close by (March) and another Class B less than 100 miles to the south. Add to that about a dozen Class D's and a bunch of nontowereds that I count on the TAC, many under the shelves of Class B and C...
Keeps us on our toes!
Remember, it isn't just the LAX Class B and the 3 +1 Cs (March has an approach facility, but they are pretty limited and SoCal takes over for them a lot), but SoCal also covers the entire San Diego B and all those underlying Ds, including a bunch of military traffic. They also sequence a bunch of traffic in and out of Mugu's airspace with the one extremely busy and one less busy D there. There is also a massive amount of flight training, insanely busy airports by movement and complexity issues (SAN's single runway, LAX requiring 24/25 ops up to 10 kts tailwinds, BUR's preferred set up, etc.).
That said, it is a great place to learn how to talk on the radio, because only a moron with a death wish would fly through the area without FF.
