Sustainability at Allegiant

We recognize the environmental impact generated by this hard-to-abate sector and are committed to integrating sustainability practices into our operations. With oversight from the Board and understanding the priorities of our stakeholders, we are dedicated to continually improving our sustainability performance through transparency, effective risk management and the cultivation of long-term and profitable business growth.

Optimization at Allegiant’s Core

Our unique business model positions us favorably in our sustainability efforts. By expertly matching capacity with demand trends, Allegiant operates a low aircraft utilization model that maximizes flying on peak-travel demand weeks and days of the week. Similarly, the seating configurations of our A320 aircraft allow us to operate more efficiently on a per-passenger basis – adding 25 seats more compared to the same aircraft operated by other US carriers. Our extensive network allows us to fly a 100% non-stop schedule taking our passengers point-to-point without adding emissions through layovers.

Key Levers for Decarbonization


2030 Decarbonization Goal

We are guided by our carbon intensity reduction goal of 10% per revenue ton kilometer by 2030, from a 2023 base year. This target focuses on our scope 1 tank-to-wake emissions.

Fleet Transition Plan

The acquisition of 50 newly manufactured Boeing 737 MAX aircraft is expected to burn up to 20% less fuel on a per passenger basis compared to our existing fleet.

Optimizing Energy Efficiency

Our dedicated Fuel Steering Committee manages fuel efficiency and implements strategies to enhance performance. This includes but is not limited to optimizing aircraft trajectory configuration and speed, and enhancing on-the-ground taxiing and handling.

Exploring SAF

By taking a proactive approach to future risk mitigation, we are engaging with Sustainable Aviation Fuel (SAF) producers. Certain SAF could provide CO2 reductions up to 95% compared to traditional Jet-A.

Addressing Scope 3

In our 2022 report, we committed to producing a sustainable procurement policy by 2025. Engaging our suppliers in sustainability efforts enhances our operational resilience, drives cost efficiencies, and increases environmental stewardship across the value chain.
