Support Sustainable Aviation Fuel (SAF).

We have set a series of ambitious emissions-related goals at JetBlue, and we are proud to have made progress through our fuel efficiency programs and the procurement of sustainable aviation fuel (SAF). Available today, SAF is a renewable jet fuel that safely drops into existing aircraft and infrastructure and can reduce lifecycle emissions by roughly 80% before being blended with conventional jet fuel.

Contribute to SAF.

While the SAF market continues to meaningfully grow year-over-year, the market is still emerging, and supply remains at less than 1% of global fuel consumption. There are multiple potential feedstocks and technology types being pursued by SAF providers, both existing and future, which will be key to growing and scaling SAF supplies. You can help us accelerate aviation's transition to SAF by contributing, and through this, demonstrating demand for less carbon intensive fuel. Your contributions will apply towards the price premium for JetBlue to purchase SAF.

Help fuel the future of aviation.

In 2024, JetBlue became the first U.S. airline to regularly supply SAF in New York at John F. Kennedy International Airport (JFK). With almost 6 million gallons of neat SAF delivered as of 2024, JetBlue has helped avoid roughly 50,000 mtCO2e since launching our SAF program.

How will my purchase reduce emissions? Sustainable aviation fuel (SAF) is an alternative jet fuel that safely drops into existing aircraft infrastructure and can reduce life cycle emissions by roughly 80% as compared to fossil-based jet fuel. JetBlue is proud to have doubled SAF in its operations year-over-year on average since 2020, taking delivery of SAF at SFO and LAX. In late 2024, JetBlue was the first airline to bring a regular supply of SAF to New York at JFK. However, SAF still makes up less than 1% of global jet fuel and support is necessary to scale the SAF market and reach industry goals. Your contribution helps with the cost premium between SAF and conventional jet fuel, allowing us to replace conventional jet fuel with SAF. JetBlue sources SAF from multiple suppliers at 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.

Can I earn Mosaic 1 status if I purchase SAF indirectly (e.g., through a partner program or third-party vendor)? The only way to earn Mosaic 1 is through the JetBlue SAF/Loyalty promotion, located at

Sustainable Aviation Fuel (SAF)

What is sustainable aviation fuel (SAF), and why is my contribution important? Sustainable aviation fuel (SAF), also known as alternative jet fuel, is an industry term used to describe non-conventional jet fuels that are derived from renewable resources, known as feedstocks. Due to the limited amount of SAF available in the market today, SAF production, distribution, and refueling infrastructure are not yet widespread. Your purchase allows us to replace conventional jet fuel with SAF by helping with the cost premium associated with SAF. JetBlue calculates the price premium as the average price of SAF above the price for conventional jet fuel. Funds will be used by JetBlue strictly to purchase SAF. JetBlue commits to utilizing 100% of the funds received, net of fees associated with service and technology. Net fees include a 10.31% service and technology fee, paid to Chooose, allocating 89.69% of your funds towards the purchase of SAF. JetBlue will not sell emission reduction claims associated with any SAF through customer contributions to another third party.

What are the benefits of SAF compared to conventional jet fuel? The core benefit of SAF is that it has lower carbon life cycle emissions than conventional jet fuel – with the potential to reduce the carbon intensity of flying by approximately 80% in unblended (neat) form. When burned, SAF and conventional jet fuel produce similar levels of emissions, but the emissions generated from SAF are already part of the carbon cycle (because they are made of renewable resources) and not extracted from the ground specifically for creating aviation fuel. This results in reduction of emissions using SAF compared to conventional jet fuel when considered over the lifecycle of the fuel. SAF is a drop-in fuel substitution, meaning it can be blended with conventional jet fuel in current aircraft engines without modifications and does not require any changes to aircraft or airport infrastructure. Furthermore, SAF production may have additional community benefits as scaling SAF production creates new economic opportunities.

Why contribute to SAF? Today, SAF is at a significant cost premium compared to conventional jet fuel due to the high cost to scale production, manufacturing constraints, and limited feedstock diversity. Through your contribution, you help JetBlue scale the emerging SAF market and support sector decarbonization. JetBlue is working to increase the availability of SAF across our network – with SAF producers, policymakers, 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 of SAF, making it more affordable, accessible, and a more regular part of flying.

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 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 life cycle, in its neat form SAF can reduce 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 infrastructure.

Is it safe to fly on SAF? Yes – SAF meets 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 on any individual JetBlue flight. In 2024, roughly 0.35% of our total fuel purchased was neat SAF.

How are my SAF contributions used? All funds collected through this promotion will be used by JetBlue strictly towards furthering additional SAF purchases. 89.69% of your contribution goes directly to the cost of SAF with the remaining 10.31% covering a service and technology fee paid to Chooose.

Emission reductions calculations

How do you calculate the amount of SAF attributes or emissions reductions associated with a given volume of physical SAF? The amount of “SAF attributes” you purchase with your contribution represents the estimated emission reductions associated with a volume of physical SAF as compared to the same volume of traditional fossil-based fuel. More specifically, this calculation shows the difference between jet fuel baseline emissions and the SAF emissions on a Well-to-Wake (WTW) basis. Jet fuel baseline emissions are calculated based on the CORSIA jet fuel baseline value in combination with Lower Heating Value (LHV) from GREET 2023. SAF emissions are calculated on a WTW basis using the volume of SAF and the associated life cycle assessment (LCA) value from the specific batch of delivered SAF, as provided by JetBlue. Both density and LHV for SAF are sourced from GREET 2023. The total emissions impact is provided in CO2e and includes CH4 and N2O per AR4 100-year NF conversion. Source: ,

Please note: the emissions reduction estimates see above are provided for educational and informative purposes only. They do not represent the actual emissions generated from your flying. For example, according to ICAO’s default values for life cycle 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 are ICAO standards. Many of the SAF producers JetBlue works with undergo audits for their carbon intensities, resulting in even lower carbon intensities and higher GHG reductions in some cases.
