Info on getting to JFK by 0500hrs (Tuesday)

Well,my time on the Island is about spent. Gotta turn my wheels back in a few hours and I need to get from Pt Jeff to JFK by 5am. Tuesday morning. I would like to take the LIRR, but I am still noit sure. Any ideas?

Unless you leave monday night, it's not gonna happen.
The earliest train out of Port Jeff is at 4:19AM. It gets to Jamica at 5:53AM. Where you would then transfer to the Air Train.

Get a car service.

Perhaps you can find a way to Ronkonkoma....but even then, I'm not sure if that line's got any trains runnin that early.
