Frequently Asked Questions
How is the Fleet Modernity Index calculated?
The Modernity Index scores an airline based on the percentage of active flights operated by verified new-generation airframes (such as Airbus A320neo, A321neo, A350, Boeing 737 MAX, 787 Dreamliner, and Airbus A220), penalizing older high-cycle airframes.
What defines an Eco Titan in the Modernity Quadrant?
An Eco Titan is a commercial airline operating a large fleet of 100 or more aircraft where modern fuel-efficient jets make up more than 50% of active operations, achieving between 15% and 25% lower fuel burn per seat-kilometer.
Why do Legacy Giants face higher transition risk?
Carriers in the Legacy Giants quadrant operate large fleets dominated by older-generation jets (such as A320ceo, 737NG, 777-200ER, and A330ceo). These airlines face massive multi-billion-dollar capital expenditure needs and extensive delivery wait times due to sold-out OEM order books.
Which aircraft types are recognized as next-generation in the carbon scorecard?
The framework tracks Airbus A319neo, A320neo, A321neo, A321XLR, A330-800/900neo, A350-900/1000, Boeing 737 MAX 7/8/9/10, Boeing 787-8/9/10 Dreamliner, and Embraer E-Jets E2 series.
