And why would he fly into Newark? JFK seems much more convenient given where his apartment is. Fuck, LGA is would be closer (timewise, IDK about pure mileage) too and he could avoid Jersey altogether.
TANxTAN - as a former upper west sider*, allow me to fill you in.
- getting to newark: 1 subway to penn station (10 mins), then a 25 min train to newark. often the cheapest airport to fly out of.
- getting to JFK: a nightmare. 60 if you hop between subway and LIRR (light rail), 90 minutes on subway.
- laguardia: 75-90 minutes, 2 subways, 1 bus.
but, but, i would never deign to take public transpo, i drive! assuming you own a car (which is a big assumption, but i believe that in the alternate reality that is the seinfeld show they all did)
EWR: 45 mins
JFK: 60 mins
LGA: 30 mins
so LGA makes sense if you're driving... and not price sensitive. parking much cheaper out in the desert that is newark.
