Using Spirit Terminal to fly? For a low-cost carrier, Spirit Airlines EWR Terminal is remarkably good. The staff was courteous, and I saved time by checking in using the kiosks. There is enough of seating close to the gates in the tidy and well-maintained terminal. There aren’t many food alternatives, but there are enough for a quick snack. It was easy and on time to board. Spirit’s terminal in Newark did a fantastic job of keeping everything organized and stress-free for a low-cost airline.
