In my experience, dealing with Spirit Airlines EWR Terminal was easy and straightforward. Self-service terminals enabled quick check-in, and attendants helped with baggage check. Easy-to-follow signage made it easy to navigate the station, and security lines moved routinely. Even though Terminal B was older, there was a good variety of food and plenty of seating near the gate. Zones were employed to board, and the flight departed on time. Everything else considered, the flight was smooth and affordable.
