Key Takeaways
• Sustainable aviation fuel (SAF) costs two to three times more than conventional jet fuel, raising airline operating expenses.
• Global SAF production is less than 1% of demand, requiring an 18,000% increase to meet U.S. 2025 targets.
• Higher costs and regulations mean airlines must raise airfares, impacting travelers, students, workers, and cross-border mobility.
Sustainable aviation fuel is becoming a word you hear more when airlines and governments talk about the future of flying. If you’re booking a flight now or planning to travel in the future, you might wonder why ticket prices could go up. The short answer has a lot to do with the price and supply of sustainable aviation fuel and how airlines respond to rules and market forces. Here, we’ll break down exactly what’s going on, why it matters for anyone traveling by plane, and what the long-term effects could be for airlines, travelers, and the environment.
What Is Sustainable Aviation Fuel, and Why Is It Important?
Sustainable aviation fuel, often called SAF, is fuel made from sources like used cooking oil, algae, crop waste, or other materials that don’t come straight from oil wells or natural gas. The big idea is that SAF creates fewer greenhouse gas emissions than regular jet fuel made from crude oil.
Governments and airlines say sustainable aviation fuel is key for making air travel cleaner. Airlines want to show they’re serious about reducing pollution, and governments are starting to require more use of greener fuels. But while SAF sounds great in theory, there’s a big problem: very little of it is actually being made, and what does get produced is much more expensive than regular jet fuel.
High Costs and Limited Supply: The Core Problems
Right now, sustainable aviation fuel costs about two to three times as much as conventional jet fuel. This isn’t just a small difference. For airlines that buy millions of gallons each year, paying double or triple adds up quickly.
Another big problem is there just isn’t enough SAF to go around. Even with all the focus on greener flying, global production of SAF is less than 1% of what’s needed to meet everyone’s demand for jet fuel. In the United States 🇺🇸, for example, just reaching government targets for sustainable aviation fuel would require an 18,000% jump in production compared to how much was made in 2022.
When something is both scarce and expensive, buyers who really need it (like airlines, especially if they face government rules) have to compete for very little supply. That pushes prices up even more.
Airlines’ Response: How Costs Get Pushed to Travelers
You might wonder why airlines don’t simply use less fuel or look for ways to cut costs elsewhere. The truth is, airlines can’t easily change how much fuel they use without flying fewer planes or cutting routes. But people still want to fly, and most big airlines want to keep offering as many flights as possible.
This is where something called “inelastic demand” comes in. In airline-speak, the demand for airplane fuel doesn’t drop much even when the price goes up. Planes have to fly, no matter what the cost. So, when airlines are forced (by rules or their own public goals) to buy more expensive sustainable aviation fuel, they usually can’t just absorb this cost. Instead, they pass much of it onto travelers by raising airfares.
Experts sum it up well: “Cost increases due to a switch in fuels can be passed through to consumers… Price-unresponsive demand creates more opportunity for high-cost fuel producers than if fuel users would drastically cut use in response.” In other words, since people keep flying even when fuel gets expensive, airlines can raise ticket prices to cover these extra costs.
New Rules and Promises Put More Pressure on Airlines
It’s not just market forces at play. Governments around the world are starting to require airlines to blend a certain amount of sustainable aviation fuel into their regular jet fuel mix. For example, countries may mandate that a specific percentage of the fuel an airline uses must be from sustainable sources. If there’s not enough SAF to go around, airlines have to grab what they can, even if prices spike.
On top of this, many airlines are making public promises—sometimes signing contracts that commit them to buy large amounts of sustainable aviation fuel far into the future. Often, these “offtake agreements” lock in premium prices, and may include higher costs if supply remains short. This can create financial risks for the airlines when they can’t find enough SAF or are forced to pay very high prices.
How Scarce and Expensive SAF Drives Up Airfares
When you put all this together, a clear picture appears:
- If SAF is hard to find and costs much more than regular jet fuel, airlines end up paying more just to keep flying.
- Most travelers and companies aren’t willing to pay much extra voluntarily for greener flights, especially when times are tough for household budgets.
- As a result, airlines find that the only way to keep their planes in the air and meet rules or their own “green” promises is to raise ticket prices across most routes, not just for those willing to pay a green premium.
As reported by VisaVerge.com, these rising costs can’t be completely absorbed by airlines, so over time ticket prices for everyone are likely to go up if sustainable aviation fuel remains scarce and costly.
Experts agree: “The main hurdles are the lack of supply, and the cost, typically double or triple the price of conventional fuels.”
Market Effects: Winners, Losers, and Unknowns
What happens in the market when sustainable aviation fuel costs this much and is so hard to buy?
- SAF suppliers benefit, since airlines must buy from them, but only if they can ramp up production.
- Airlines face rising operational costs, which can threaten their profits, especially for smaller carriers or those in competitive markets.
- Travelers (you) may find airfares rising in the coming years, regardless of whether you’re flying for business or vacation.
- Governments may have to balance the drive for greener flying with concerns over making flying too expensive for everyday people.
Summing Up the Main Causes Raising Ticket Costs
Let’s look again at the key reasons sustainable aviation fuel is likely to raise airfares:
- High Cost Per Gallon: Since SAF is two to three times more expensive than regular jet fuel, airlines face much higher operating costs.
- Low Production Volumes: With less than 1% of the needed amount being made, airlines sometimes resort to expensive last-minute deals to secure SAF, driving prices even higher.
- Inelastic Jet Fuel Demand: Because airlines can’t easily cut fuel needs, any price hike tends to get passed onto ticket buyers.
- Regulatory Mandates: New rules force airlines to buy sustainable aviation fuel, no matter the price, leaving them with fewer options.
- Limited Willingness to Pay: Not enough travelers or companies are ready to pay much extra for “green” tickets, so airlines can’t only charge a premium for special eco-friendly seats—everyone ends up paying more.
Here’s a simple summary table showing how these factors work together:
| Factor | Effect |
|---|---|
| High Cost Per Gallon | Raises airline expenses due to fuel purchase |
| Low Production Volumes | Forces costly last-minute SAF buys |
| Inelastic Jet Fuel Demand | Makes it easier to pass costs to customers |
| Regulatory Mandates | Requires expensive purchases, even if unaffordable |
| Limited Willingness-to-Pay | Not enough buyers for green premium, so fares rise |
Other Risks: Food Crops vs. Waste Oils
Some companies making sustainable aviation fuel are looking for new sources of material to make more of it. At first, much of the supply came from waste oils—like used cooking oil from restaurants. But there’s only so much of that to go around.
To boost supply, some producers are turning to crops like corn or soybeans. While this can help ramp up production, there are some big worries. Using food crops for fuel could take away from what’s available for people and animals to eat. It might also mean that the environmental benefit of SAF (less pollution) is lower than hoped, especially if more land is cleared or more fertilizer is used.
Even though these risks are serious, they don’t directly raise airfares unless new rules follow—like if governments put stricter limits on crop-based fuels, or if public opinion shifts and pressures lawmakers to step in.
What’s Needed: How to Lower Airfares and Protect the Environment
There’s broad agreement that the only real way to stop continuing increases in airfares, while also making flying cleaner, is to make much more sustainable aviation fuel and bring prices down. That means investing in new factories, encouraging more innovation in how SAF is made, and making sure there’s a steady market for it.
To meet targets, the United States 🇺🇸 alone would need thousands of times more SAF than what was made in 2022. Without massive new investments and breakthroughs, prices are not likely to fall anytime soon.

Long-Term Implications for Immigration and Cross-Border Mobility
For people who travel internationally, including those moving to a new country for work, study, or family, higher airfares could have other effects beyond just the cost of your ticket. Here’s how the changes in sustainable aviation fuel can matter for immigration:
- Rising ticket prices can make it harder for families to visit each other or for people to move internationally. This might affect students, migrant workers, and people applying for visas who need to travel.
- Higher flight costs can affect international companies, including those who rely on employees moving between countries for business needs.
- In the future, if flying becomes much more expensive overall, governments and employers might look for different ways to support or offset travel for visa and immigration purposes.
While it’s unlikely that any one policy or market change will stop people from moving or traveling for good reasons, persistent increases in ticket prices can make a real difference in how often people can afford to visit family, attend school, or move for a job.
Different Views: Is There a Better Way?
Not everyone agrees on how fast airlines should ramp up the use of sustainable aviation fuel or who should cover the costs. Some experts believe that governments should do more to subsidize or help the industry produce more fuel, instead of putting all the cost onto travelers. Others think that the real solution will only come when new types of fuel are invented that are just as cheap as regular jet fuel. And some point out that as technology gets better and more companies enter the market, the price of sustainable aviation fuel will likely fall over time.
For now, the big issues are:
- Not enough supply to meet government rules and airline promises;
- Price is out of reach for many airlines to use at scale;
- Most people are not ready to pay double or triple for a ticket just because it’s greener.
What to Expect as a Traveler, Student, or Worker
If you’re planning to travel or move between countries in the next few years, it’s smart to:
- Keep an eye on ticket prices and plan your travel in advance.
- Check airline websites for information on how they are blending sustainable aviation fuel, as some carriers may offer the chance to offset emissions or pay for greener options.
- Consider other ways to support cleaner travel, such as flying with airlines that make clear commitments or choosing non-stop routes (which can be more fuel-efficient).
Governments, airlines, and travelers will continue to debate how to share the costs and benefits of reaching a greener future in aviation. You can stay up to date on these changes by following official updates from regulators and visiting reliable sources like VisaVerge.com for analysis and investigation into evolving travel and immigration issues.
Final Thoughts
Air travel is likely to get more expensive in the coming years if the supply of sustainable aviation fuel doesn’t rise and its price doesn’t drop. These changes are shaped by the high costs of SAF, strict government rules, and limited ability among airlines and passengers to absorb higher prices. Until affordable, scaleable solutions emerge, higher operating costs for airlines will likely continue to mean higher ticket prices for travelers—including those moving for work, study, or family.
As countries and companies work to find answers, travelers should keep watching, plan ahead, and make choices that match their budgets and values. Whether flying for immigration, business, or leisure, knowing what’s behind changes in airfares can help you make better decisions for your future journeys.
