I plan on flying on 7/6/19 and back on 7/21/19 ... is this considered long term? what would it cost me? do I need to make a reserve a spot?

JFK long term parking no reservations required and also not available right now. Per 18$ max first 24hrs 18$ then every 8 hrs 6$. Ots easy and convenient. I parked 11days no issue.

It is long term parking. I parked for 3 days and the cost was around $22 a day without a discount. Search for a coupon online. It is probably a good idea to reserve a spot. But not absolutely required.
