I could arrive in JFK one night, and catch a cheap flight to my smaller city the next morning. So, I'm thinking of over-nighting there.
What are my best options? Is sleeping in the airport feasible? What are the costs of hotels, are they attached to the airport / how much do they cost / how hard are they to get to / how much does it cost to get to them?
TO BE CLEAR: In General, what are the rough price ranges of cheap options, including the feasibility of sleeping at the airport?
Side notes: These flights have to be bought separately, non-negotiable--if I ever put my small city in as final destination, flights are always $400 more than if I buy them separately.
I'm also explicitly trying to catch this flight so I can fly on same flight with my brother, and there is no reasonable flight later that same night from the same airport to my small town.
