Is it worth a trip from Manhattan to the Marine Air Terminal just to see it? I only saw it once on a flight about 12 years ago. I remember there was a mural. One proposal is a 1 pm arrival to see the Marine Air Terminal then see Terminal B (or even Terminals C and D) before it gets torn down then head to JFK for a 6 pm flight.

Or is there a better way to spend 2 hours more in Manhattan and go directly to JFK?
