Mexican low-cost carrier Interjet has ordered 80 of CFM International’s LEAP-1A engines, which it will use to power its fleet of 40 A320neo family aircraft. The order, which was announced at the Farnborough Airshow, is worth $2.9bn at list prices and includes a long-term support package. Under the terms of its agreement, CFM will guarantee maintenance costs for all 80 LEAP-1A engines on a dollar-per-engine-flight-hour basis. Interjet operates scheduled flights with 41 CFM56-5B-powered A320s from Mexico and to destinations in the Caribbean, Central America, North America, and South America. The airline will use the A320neos, which were ordered in November 2012, to renew and expand its fleet.
