The bottom line is fairly simple given that the physical space between a major highway and the construction site leaves just so much space:

1. Limit vehicles and divert everyone into some form of shuttle system to offsite areas. This would include taxis, car service, and private vehicles.
2. Limit capacity into the airport, e.g. # of passengers (rotations already limited).
3. Massive airport use fee for non-public vehicles, e.g., private vehicles, taxis, car service (add $20 to the cost of a ride and see how many people will hop a bus to an off site location)

None of these are particularly appealing to any carrier which is the primary service point for HVC's and serves NY's financial district. However, there are plenty of people who would pay $20 extra to have priority access to the curb and leave the rest of the populace simmering in a traffic jam.

This is going to continue through 2020 (at least). People who say that they will consider elsewhere don't know NYC. Neither JFK nor EWR are particularly convenient, the HVC's who make the world go round and support the airfare structure in the market are not going to take public transportation from either and most of them can work from a car just as well as they can from a desk, so the traffic is not as much of a bother.
