Modern amenities including improved security checkpoints, roomy waiting spaces, and a range of restaurants and shopping options make this recently refurbished Spirit Airlines EWR Terminal a more effective and contemporary place to fly. Easy access to domestic flights, including Spirit's reasonably priced itineraries, is provided by Terminal A. In order to save extra costs, passengers should be aware of Spirit's baggage restrictions and anticipate inexpensive, basic service.
