How easy is it to go from New York La Guardia to Newark Liberty International airports?
There’s no way your leaving the airport crossing manhattan and going all the way to NJ during the Monday morning rush hour. I could give you all the different ways to do it, taxi, shuttle bus, trains, but trains would take too long and traffic will not move. It’s just not going to happen. Find another way. If you don’t leave LGA until after 9:30, and you have a good 5-6 hours you can do it. Flights into LGA are notoriously late, so 5-6 hours is a minimum to switch airports across manhattan. Try JFK as an alternative to Newark, it’s a lot closer to LGA and also fly’s international.
