Depends on what fleet you're on. Most widebody departures are out of JFK. Over 30% of 717 trips depart out of EWR. Technically the NYC "hub" consists of JFK and LGA, we don't have a big presence in EWR. Trips have to get you back to the airport you began your trip from or they will limo you back. We have employee parking at all 3. LGA is soon to be "valet" (what could go wrong?)
