describes non-conventional jet fuels produced from more sustainable resources (also referred to as feedstocks). While producing conventional jet fuel involves fossil fuel extraction, SAF production relies on alternative feedstocks which can, for example, be from waste materials from forestry and agriculture, used cooking oil, and beyond. SAF is compatible with existing aircraft infrastructure, making it a safe, easy substitute for conventional jet fuel. What are the benefits of SAF compared to conventional jet fuel? The core benefit of SAF is that it has lower net carbon lifecycle emissions than conventional jet fuels – with the potential to reduce the carbon intensity of flying by approximately 80% in unblended form. Put simply, the process of making SAF recycles carbon that is already in circulation as opposed to extracting additional carbon from the ground (thus releasing CO2 that has been – and would otherwise continue to be – sequestered for millions of years). As a result, SAF has a lower net carbon footprint as compared to conventional fuels. SAF also works seamlessly with existing aircraft engines, known as a “drop-in fuel”, meaning it does not require any changes to aircraft or airport infrastructure. Furthermore, SAF production may have additional community benefits as scaling SAF production creates new industries and economic opportunities. Please note, the results you may see here are provided for educational and informative purposes only – they are estimates to help you understand anticipated emissions benefits from SAF. According to ICAO's default values for lifecycle emissions, SAF derived from tallow produces 22.5 gCO₂e/MJ and 13.9 gCO₂e/MJ for SAF derived from used cooking oil compared to 89 gCO₂e/MJ for conventional petroleum-based jet fuel. This is approximately a 74-85% greenhouse gas (GHG) emissions reduction assuming default values per ICAO standards. Many of our SAF producers undergo audits for their carbon intensities, resulting in even lower carbon intensities and higher GHG reductions in some cases. Why contribute to SAF? Currently, SAF has a significant cost premium compared to conventional jet fuel. When you contribute to JetBlue’s SAF purchases, you help allow us to source more renewable fuel for flying and help scale the emerging SAF market. We've been working with our business travel partners over the past few years to help fund some of our purchases of SAF. Now, via Chooose, we can extend this opportunity to all of our customers and all types of travelers. [Sharing is caring.] With your contribution to SAF, we’re saying that you—the customer—care about sustainability and want to see more sustainable fuels in aviation. There’s a limited amount of SAF available to airlines, and the cost premium compared to typical jet fuel means there aren’t many producers yet. JetBlue is working to increase the availability of SAF across our network—with SAF producers, policy-makers, infrastructure operators, and airport authorities—and we hope to see much more SAF availability in the coming years. With our collective efforts, we can begin to bring down the cost premium to SAF, making it more affordable, accessible and a more regular part of flying. What is SAF made from? SAF can be produced from a variety of sustainable resources, also known as “feedstocks.” Today, JetBlue is taking delivery of SAF made from waste animal fats and greases, such as used cooking oil and tallow, and presently only sources feedstocks certified by ISCC or RSB (see to learn more) to help us ensure a high-level of integrity in sustainable fuel while minimizing inadvertent biodiversity impacts or induced land use changes. Importantly, JetBlue does not source SAF from palm oil or PFAD residues, due to concerns related to potential deforestation or sustainable harvesting. What is neat SAF? What is blended SAF? Neat, or unblended, SAF is the alternative, lower-carbon jet fuel derived from non-petroleum based matter. In a technical setting, neat SAF is defined as a synthetic blending component of synthesized hydrocarbons that meet the requirements in any one of the annexes of the ASTM D7566 pathway (read more in .) Depending on its processing pathway and lifecycle, in its neat form SAF can reduce aviation emissions by approximately 80%. Blended SAF is the mixture of neat SAF with traditional fossil-based jet fuel. Depending on the processing pathway, a mixture of up to 50% SAF with fossil-based jet fuel is permitted. In short, “neat” SAF refers to a volume of fuel that is only SAF, whereas “blended” SAF refers to a volume of fuel that is inclusive of both the SAF and the fossil-based jet fuel that it has been blended with. Blended SAF serves as a “drop-in” product for existing aircraft and infrastructure. Is it safe to fly on SAF? Absolutely, SAF meets exactly the same quality and safety requirements as conventional jet fuel. JetBlue has been regularly incorporating SAF into our operations since 2020. Does every JetBlue flight have SAF? JetBlue purchases SAF that is integrated into communal fueling infrastructure. We are unable to guarantee SAF has been blended into the fuel used on any specific JetBlue flight. Today, roughly 0.35% of our total fuel purchased is neat SAF. How are my SAF contributions used? Your contribution helps cover the difference in cost between SAF and conventional jet fuel, allowing us to replace conventional jet fuel with SAF. We have multiple SAF suppliers with varied price points based on location, feedstocks, etc. For this initiative, we calculate the price premium as the average price of SAF above the price for conventional jet fuel. Disclaimers:

• A service and technology fee, equivalent to 10.31%, will be paid to Chooose. This fee is included in the total contributions and does not contribute towards the purchase of SAF.

• Contributions are voluntary, non-refundable, and non-tax deductible. They do not constitute a surcharge or ancillary fee in addition to the customer’s airfare or other services/products purchased by the customer from JetBlue or its affiliates.

• Contributions are non-transferable and cannot be used as a credit for airfare or other services offered by JetBlue or its subsidiaries, unless otherwise expressly offered by JetBlue.

• JetBlue does not make any assurances as to the timing of the use of Contributions. JetBlue’s use of Contributions is partially dependent on factors outside of its direct control, such as the market availability of SAF/blended SAF products. JetBlue retains the right to make SAF purchasing decisions regarding the use of Contributions.

• Contributions do not grant customer title to Scope 1, 2, 3 greenhouse gas emissions reduction credits, or any other environmental credits or attributes, which are retained by JetBlue and/or its business partners (i.e., SAF producers, blenders, etc.). Scope 3 emissions reduction claims associated with any SAF purchased through customer contributions will not be sold to any third party.
