Sustainability at Allegiant

At Allegiant, we’re proud to offer the nonstop routes that bring people together - and just as we understand the joy of connection, we also recognize our place in a hard-to-abate industry. That’s why we’re committed to doing our part: strengthening accountability across our operations, investing in better data and smarter practices, and planning for long-term, sustainable growth. With governance starting at the Board level and a clear 2030 carbon-intensity reduction target, we track our emissions and are building the systems needed to measure and manage our broader climate impact.

Our Decarbonization Levers

To reach our 2030 decarbonization goal, we’re taking a multifaceted approach. Alongside continuous optimization of our operating model for greater efficiency, we’re leveraging two key pathways to reduce emissions. We remain flexible and data-driven, actively evaluating emerging technologies, market developments, and products to identify the solutions that best align with our business and long-term climate strategy.

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.
