Delta’s announcement of new state-of-the-art aircraft from Boeing and Airbus, a significant milestone toward the airline’s sustainability goals, as well as a major next-generation engine service agreement with CFM International were among the show’s highlights.

The service agreement was made in conjunction with Delta’s order for 100 next-generation Boeing 737-10 aircraft, which will be powered by the LEAP-1B engine.

The aircraft will be 20%-30% more fuel efficient than the retiring Delta planes it will replace, making the agreement an important step in Delta’s journey toward a sustainable future for aviation.
