Yes if you mean the airport in New York City. Virtually all airports in the US are open Sunday.
no, Newark airport is in NJ, whereas La Guardia & JFK are in New York.
# La Guardia # JFK # Newark
JFK, La Guardia and Newark.
Paris to Newark (JFK) is 6Hours or so.
I think LaGuardia by a little.
LaGuardia is closer. Both JFK and LaGuardia are in Queens. Newark is in New Jersey.
About 250 miles, but if you need to go from JFK to Boston there are a lot of flights into Logan.
Newark, LaGuardia & JFK
Assuming you're traveling to Manhattan, any of the three major airports will work (LaGuardia, Newark or JFK). However, if you are planning to use public transportation, you should choose Newark or JFK, because LaGuardia does not have a rail station. Newark Liberty International Airport is served by NJ Transit and Amtrak trains. JFK is connected by AirTrain to the subway and to the Long Island Rail Road station in Jamaica, Queens. (The trip time from Newark is usually slightly shorter.)
Answer to your question is no, they don't fly out of Newark. They do fly out of JFK in New York City. You can look at Iberia.com/us to see where their US Departs are from.
It would take between 45 and 54 minutes to get from JFK airport to Newark airport. The exact time will depend on which route you take, and the traffic at the time that you are on the road.
