Miramar-based Spirit Airlines announced Thursday that it had ordered 20 new Airbus A321 planes.
The low-cost airline already had an order for 96 aircraft that are scheduled to be delivered between 2015 and 2017. Spirit also chose to convert 10 A320 orders to A321 models instead; those planes will be delivered in 2017 and 2018.
Spirit did not disclose what it agreed to pay for the planes.
All off the 30 A321 aircraft will be built with wingtip devices called “Sharklets” that are meant to improve fuel efficiency.
Spirit will use the planes for routes in the United States, Caribbean and Latin America, the airline said.
