JetBlue Aims To Retain Its Cost Advantage With Addition Of New Airbus A321s

At a recent presentation, JetBlue mentioned that the new Airbus A321s are 10-15% more cost efficient than its existing fleet of Airbus A320s. In addition, the sharklets that the carrier is installing on its existing A320s are to improve the fuel efficiency of those airplanes by 3-4% on long haul transcontinental routes. We figure cost savings from these measures will help reduce JetBlue?s fuel costs, which last year constituted nearly 38% of its total operating costs.
