Sorry to bump this thread - but I am looking at booking a LGA/JFK itinerary. Has anyone had recent experience doing this? I am looking at a 4 hour connection. Is that enough time arriving LGA at 7:00pm on Friday (in January) and departing JFK at 11:30pm?
Regardless of who pays, that is plenty of time. I've done it with about 2 1/2 hours between flights toting my luggage from airport to airport by taxi.
