From the north, talk to LGA approach.

LGA approach? Is that different from the tower or NY approach? Is this on
119.95?

From Linden, call up EWR.

On 127.85 or 118.3. That's where I became confused. Is 127.85 what you're
calling "EWR approach"?

If you're
over the Raritan bay, call JFK.

Yes? EWR seems the closer choice there.

If you call the wrong one, they will
direct you to call the airport with jurisdiction over your area. When this
happens, they will sometimes give you a frequency to call. My limited
experience here leads me to advise you to ignore that. If EWR tells you to
call JFK approach on xxx.x, you will be wasting your time to do it. Look
up the JFK approach frequency on the sectional chart and call that.

Is "JFK approach" 125.25?

So what is this "airport approach" thing? Where does it fit in the Universe
(as I understand it) which includes TRACON and Tower?

Thanks...
