I had a seamless experience flying with Spirit Airlines EWR Terminal. The airline is based at Terminal 1, which is convenient to find and has acceptable amenities. Check-in was fast, thanks to self-service kiosks and friendly staff. Security lines were moving quickly, although rush hour can be busy. The gate area had plenty of seating, and although food choices were limited, they were acceptable. Boarding was structured, and the flight took off on schedule. Overall, Spirit Airlines offers a low-cost but effective experience.
