On: Gotham Air: Manhattan to JFK in 6 minutes for $99

35 minutes is a stretch. Starting at Penn Station, Google Maps has 52m as the minimum and 1h11m as the max.

And that's from Penn Station. Add the time it takes to get to Penn Station from where you're going, it can easily be between 1h30m and 2h. I did this trip yesterday, and from where I started in Soho until the airport, it was 1h45m.

Sure, but are you going to be able to get to the helipad any quicker than getting to Penn?

There's only one way to find out.
