HONOLULU, March 25, 2013 /PRNewswire/ -- Having reached key labor agreements with its pilot and flight attendant unions on the introduction of new aircraft, Hawaiian Airlines today announced that it has signed a definitive purchase agreement with Airbus to acquire 16 new A321neo aircraft between 2017 and 2020, with rights to purchase an additional nine aircraft.

The long-range, single-aisle A321neo will complement Hawaiian's existing fleet of wide-body, twin-aisle aircraft used for long-haul flying between Hawai'i and the U.S. West Coast. "Adding the superior comfort and operating efficiencies of the A321neo will secure Hawaiian's position as the Hawaii market leader in service quality, cost efficiency and choice of destinations from the U.S. West Coast throughout this decade and beyond," said Mark Dunkerley, president and CEO of Hawaiian Airlines. "The A321neo will be the most fuel-efficient aircraft of its type after its introduction in 2016. With its slightly smaller size, we'll be able to open new markets that are not viable for wide-body service, while also being able to augment service on existing routes to the West Coast of North America," Dunkerley added. "Airbus prides itself on being part of our customers' growing successes, and this order is the perfect example of how the right plane at the right airline can alter not just a business culture, but a local community," said John Leahy, Airbus Chief Operating Officer, Customers. "The A320neo Family brings a further greening of our product line, and considering the environmental consciousness of the Hawaiian people, this aspect of the aircraft is another driver for eco-friendly, sustainable growth at the airline. It's also the most comfortable single-aisle flying today." Terms of the purchase agreements were not disclosed. The order has a combined list-price value of approximately $2.8 billion if all purchase rights are exercised. Hawaiian's A321neo aircraft will seat approximately 190 passengers in a two-class configuration (First and Coach) and have an operating range of 3,650 nautical miles. Hawaiian's A321s will offer the more comfortable seat widths found in its twin-aisle A330s.
