Sustainability

We believe in being as direct with our
impact as we are with our routes.

we’re progressing towards a better future.

Allegiant has a 2030 decarbonization target of reducing tank-to-wake emissions by 10% per revenue ton kilometer, against a 2023 baseline. In 2024, our carbon intensity (tank-to-wake) was 894 gCO2e/RTK.

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 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 (based on the A320). Our extensive network allows us to fly a 100% non-stop schedule taking our passengers point-to-point without adding emissions through layovers.

The Fleet

We’re improving fleet efficiency by retiring older, less fuel-efficient engines and introducing new aircraft. Our order of 50 Boeing 737 MAX aircraft could reduce emissions by 20% on a per passenger basis compared to our retiring fleet.

Sustainable Aviation Fuel

We recognize that sustainable aviation fuel (SAF) is one of the most important levers for meaningful emissions reduction in aviation, even as its availability and affordability remain limited. To begin building the partnerships we’ll need in the future, we issued an RFP to engage with fuel providers and explore credible, low-carbon options. Although we won’t require SAF until later this decade, we’re actively involved in state-level policy efforts aimed at supporting the supply and demand needed to accelerate SAF production.
