Spirit Airlines' fleet of Airbus A319-100, A320-200 and A321-200s have seat widths of just less than 18 inches and 28–31-inch pitch. Note seats on the A320s don't recline. It is possible to upgrade (in advance or onboard) to Spirit's Big Front Seat option, offering greater pitch and width. Light in-flight food and beverages may be purchased via credit card as Spirit operates a cashless system onboard.
