I'm with you that LGA is crappy, but it's not that small. It's the 20th busiest airport in the United States, and handles 23% of the total NYC air traffic. Neither EWR nor JFK have enough spare capacity to pickup that slack. https://en.wikipedia.org/wiki/List_of_the_busiest_airports_in_the_United_States https://en.wikipedia.org/wiki/List_of_the_busiest_airports_i...

Well in that case, they should expand the other two. Things would probably be a lot more efficient in that airspace too after downsizing to only two airports.

  If you end up with the same amount of traffic as before, just at two airports instead of three, how does it make the airspace more efficient?

    Better centralization. Having three control towers having to coordinate traffic between them is more chaotic than two or one. And it's more orderly to have planes coming in to fewer sets of runways.

      Having TRACON work with three towers instead of two doesn't sound any more difficult. I thought that the towers mostly just took already-sequenced traffic from TRACON and landed them, and handed departing traffic off to TRACON once they left the runway. As for fewer sets of runways, that sounds harder to me, not easier, since you have more traffic coming into the airport and that traffic has to be sequenced and deconflicted with all the other traffic coming into that particular airport. I could be wrong on this, my interactions with ATC are limited to occasionally listening to DCA tower while watching the planes land, and every so often being the point of contact to call the local TRACON to notify them of our glider operations.

        Fewer sets of runways seems like it should be easier, because the runways can be set up to be parallel to each other, so planes can all come in on the same approach and land in parallel. That's how they do it in Phoenix, with three parallel runways. With more airports, you have planes all going different directions instead. Besides, it seems like it'd be better to push some of that air traffic away from the city center, and free up some extremely valuable real estate. If they'd put in some better public transit to those two airports, people would be able to get in and out of the city a lot faster. Why can't they build actual subway lines to them anyway, instead of having to make slow and crappy, special trains to them which aren't on the main lines and then require time-consuming transfers?

Have you been to the refurbished Delta terminal? It is sparkling new with iPads for pre-paid food and drink ordering and charging at every seat.
