Republic Airways Holdings (RJET), a unit of Frontier Airlines, has confirmed an order with Airbus for 60 A320neo (New Engine Option) and 20 A319neo aircraft which follows a MoU in June this year.

The aircraft will be powered by CFM’s LEAP-X engines and will also feature large wingtip devices, known as Sharklets.

The Sharklets and LEAP-X engines will offer a 15% fuel saving, reducing annual carbon dioxide emissions by 3,600t per aircraft.

The aircraft will be flown by Republic’s Frontier Airlines subsidiary.
