Phillips 66 Aviation, One Hundred Years in the Fuel Business, and the Refiner-Direct Model Heading into NBAA-BACE Twenty Twenty-Six

Phillips 66 Aviation is entering NBAA-BACE 2026 marking 100 years in the aviation fuel business - a milestone that carries strategic weight at a moment when the entire fuel supply chain is under pressure from SAF mandates, unleaded avgas transitions, and tightening chain-of-custody requirements. The company’s core argument is simple: refinery-to-wingtip supply control matters more now than it ever has. Here’s why pilots and flight departments should pay attention.

A Century of Aviation Fuel: How Phillips 66 Got Here

Phillips Petroleum Company was founded in 1917 in Bartlesville, Oklahoma by brothers Frank and Lee Phillips. Their early drilling in the Oklahoma Territory produced a string of dry holes before the wells came in - and then they drilled 66 consecutive producers without a single dry hole. That streak became the brand name, and the story became part of American energy history.

By the late 1920s, aviation was no longer a curiosity. The airmail routes were operational. Lindbergh had crossed the Atlantic. The military understood fuel supply as a strategic asset, not just a logistics problem. Phillips moved into aviation fuels deliberately, sponsoring national air races in the 1930s and associating the brand with performance and reliability before the country went to war.

The World War II Fuel Standard That Shaped Aviation

The scale of wartime aviation fuel production is difficult to appreciate today. In 1943, the United States was producing aircraft faster than any nation in history could match - thousands of airframes rolling out of factories in California, Kansas, New York, and Texas. Every one of them required 100-octane avgas or better.

This wasn’t a preference. It was a requirement. High-performance piston engines like the Pratt & Whitney R-2800, the Allison V-1710, and the Rolls-Royce Merlin - which powered the P-51 Mustang on escort missions all the way to Berlin and back - demanded it. At altitude and in combat, the difference between high-octane fuel and a lower grade meant the difference between climbing to the fight or watching the enemy climb above you.

Phillips built refinery capacity, pipeline networks, and terminal distribution systems to meet that wartime demand. The infrastructure they constructed in the 1940s became the foundation of the postwar U.S. petroleum industry.

Navigating the Jet Age Transition

When turbine engines began replacing pistons in commercial aviation in the late 1950s, the fuel changed fundamentally. Jet-A is kerosene-based, not gasoline-based. The production process is different. The handling requirements are different. The specifications are unforgiving.

Jet-A must meet tight, non-negotiable standards under ASTM D1655. Freeze point must remain low enough to keep fuel fluid at cruise altitudes where temperatures drop below minus 50 degrees Celsius. Flash point must be high enough to prevent ignition from static discharge or hot ramp surfaces. Thermal stability is critical because modern turbines push fuel through tight passages and heat exchangers - an unstable product leaves deposits that degrade performance and damage hardware.

Phillips developed the refining processes for jet fuel production, built distribution relationships with the expanding commercial airline infrastructure, and grew through the jet age, the wide-body era of the 1970s, and the business jet boom of the 1980s and ’90s. By the time the modern business aviation market took shape, Phillips had been in the aviation fuel business for most of the previous century.

What the Refiner-Direct Model Actually Means for Operators

The refiner-direct model is the centerpiece of Phillips 66 Aviation’s current positioning, and it deserves a clear explanation.

The aviation fuel supply chain has several distinct layers: the refiner processes crude oil into finished product; terminal operators receive and store bulk product; distributors move fuel from terminals to airports; and FBOs receive, store, and deliver it to aircraft. In a conventional distribution model, the fuel in your tanks may have changed hands two or three times between the refinery gate and your wingtip. Each handoff is a separate commercial transaction, a separate quality verification, and a separate opportunity for something to go wrong.

Fuel quality events in aviation are rare but real. Water contamination from poorly maintained storage tanks. Fuel that passed the field test but was marginal on specification. Cross-contamination at multi-product terminals where shared piping and inadequate purge procedures create risk. Every additional link between refinery and aircraft is another potential failure point.

By maintaining documented supply relationships directly from their refineries to branded airport partners, Phillips 66 Aviation keeps chain-of-custody documentation more traceable and the number of intermediary steps lower. For operators flying under a Part 135 charter certificate or a corporate flight department operating under Part 91K, that documentation isn’t optional - auditors require it and insurance underwriters ask about it. For private owner-operators without those formal compliance requirements, the benefit shows up in price consistency and network reliability.

Why This Matters at NBAA-BACE 2026

NBAA-BACE is the annual arena where fuel release agreements get evaluated and negotiated. The National Business Aviation Association represents corporate flight departments, charter operators, fractional providers, aircraft manufacturers, avionics companies, maintenance organizations, and fuel suppliers across the industry. Their annual Business Aviation Convention and Exhibition draws between 25,000 and 30,000 attendees over three days and features a static display ramp of turboprops, light jets, midsize cabins, and ultra-long-range aircraft.

For fuel companies, NBAA is where relationships with flight department managers and directors of aviation get built and renewed. A corporate aviation manager responsible for a fleet of three medium jets is thinking about several hundred thousand gallons of fuel annually. Multiply that across the population of business aviation operators at NBAA, and the volume of purchasing decisions shaped by those three days of conversations is enormous.

Phillips 66 Aviation arriving at that conversation with a 100-year narrative is making a specific argument: longevity is a proxy for reliability. A company that has been in the business since 1917 and has navigated every major transition in aviation fuel history - piston to turbine, domestic to global supply - carries an implicit promise that it will be present for the next transition too.

The SAF Question Phillips 66 Is Positioned to Answer

Sustainable aviation fuel (SAF) is the largest single issue in aviation fueling right now. Produced from non-petroleum feedstocks - used cooking oil, agricultural residues, and synthetic chemical pathways - SAF blended with conventional Jet-A at ratios currently approved up to 50 percent meets the same ASTM D1655 specification as conventional Jet-A. The turbine doesn’t know the difference. The carbon accounting looks very different.

Europe has already moved. The Refuel EU Aviation regulation mandates a 2 percent SAF blend at EU airports in 2026, scaling to 6 percent by 2030 and 70 percent by 2050. The United States has stated similar long-term ambitions, though the regulatory pathway is developing more gradually. Flight departments are already being asked by their host companies to document SAF usage as part of broader sustainability reporting.

Producing SAF at scale is a refining challenge, not just a feedstock challenge. It requires processing infrastructure and quality management systems that take decades to build. A fuel company with a century of refining expertise and existing infrastructure is better positioned to bring documented, verified SAF blends to market than a distributor functioning purely as a logistics intermediary. This is a central element of Phillips 66 Aviation’s NBAA-BACE 2026 argument.

The 100LL Phase-Out and What Refiners Decide Next

100 low lead (100LL) remains one of the last widespread consumer uses of tetraethyl lead in the United States, and its phase-out is underway. The FAA has issued supplemental type certificates for unleaded alternatives including GAMI’s G100UL and Swift Fuels’ 100R, both engineered to deliver the anti-knock quality that high-compression and turbocharged piston engines require.

The terminal and distribution infrastructure to move unleaded avgas across the national system is still being built out. Phillips 66 is a 100LL producer, and the investment decisions they and other major refiners make about unleaded avgas production capacity will directly shape how smooth or rocky the transition is for the piston fleet. This is not a pilot-level decision - it is a refinery-level decision - which is precisely why refiner presence and commitment in the business aviation conversation matters.

Key Takeaways

• Phillips 66 Aviation enters NBAA-BACE 2026 with 100 years of aviation fuel history dating to the company’s founding in Bartlesville, Oklahoma in 1917.
• The refiner-direct model reduces chain-of-custody handoffs between refinery and wingtip, making quality documentation cleaner - a compliance asset for Part 135 and Part 91K operators, and a pricing/reliability asset for owner-operators.
• SAF mandates are already active: the EU requires a 2% SAF blend at all EU airports beginning in 2026, rising to 70% by 2050. Refining infrastructure, not just feedstock sourcing, determines who can deliver at scale.
• The 100LL phase-out is progressing, with FAA STCs issued for GAMI G100UL and Swift Fuels 100R. Distribution infrastructure is still developing, and major refiner investment decisions will shape the transition timeline for the piston fleet.
• NBAA-BACE remains the primary venue where fuel release agreements - which govern pricing and supply access for corporate and charter operators - are evaluated and negotiated. A supplier’s longevity, supply chain depth, and SAF capability are increasingly central to those conversations.
