Book & Claim SAF Now Available Through Integrity Flight Support and 4AIR
/A Smarter Way to Fly Sustainably — Without Changing Your Fuel Supply Chain
As part of their ongoing commitment to environmental stewardship and innovation in aviation, Integrity Flight Support is proud to announce its partnership with 4AIR, offering Sustainable Aviation Fuel (SAF) through a flexible and accessible program known as Book & Claim.
What is SAF?
Sustainable Aviation Fuel, or SAF, is a renewable alternative to conventional jet fuel. Rather than being derived from petroleum, SAF is made from sustainable feedstocks, including used cooking oils, tallow, and municipal waste, with the potential to include algae or power-to-liquid fuels in the future.
SAF is a “drop-in” fuel, meaning it works seamlessly with existing aircraft and fueling infrastructure. When blended with conventional Jet-A fuel, SAF meets all safety and performance standards (ASTM D1655 or DEFSTAN 91-91), and significantly reduces lifecycle carbon emissions — up to 90% with neat SAF, and typically 20–25% when blended.
Despite its benefits, SAF remains scarce at most airports due to logistical and supply challenges — that’s where Book & Claim comes in.
✈️ What is Book & Claim — and How Does It Work?
Book & Claim is a long-standing chain of custody model that enables flight operators to purchase the environmental benefits of SAF, even when physical SAF isn’t available at their airport.
Here’s how it works:
Producers deliver SAF into a local pipeline or airport fuel system near where it’s made, minimizing transportation emissions and costs.
The fuel is sold as regular Jet-A (without its sustainability attributes) to a third party.
You, the operator, purchase the environmental attributes of that SAF, known as a “green premium.”
You get to claim the emissions reductions as part of your carbon footprint reduction strategy, while contributing to increased demand and future scalability of SAF.
This approach is similar to how Renewable Energy Credits (RECs) work in the electricity market. The actual molecules of SAF don’t reach your aircraft, but your purchase helps displace fossil fuel use globally, encourages more SAF production, and allows you to meet sustainability targets — all without changing where or how you fuel.
✅ Why Book & Claim Makes Sense
Immediate Emission Reductions: Supports decarbonization goals without needing physical SAF delivery.
Market Expansion: Helps SAF producers reach broader markets, boosting industry viability.
Cost Efficiency: Reduces distribution costs and makes SAF more affordable over time.
Verifiable Transactions: All transactions are third-party verified through platforms like 4AIR’s Assure SAF Registry, ensuring emissions reductions are never double-counted
By participating in Book & Claim through Integrity Flight Support, your operation not only becomes more sustainable, it becomes a climate champion.
