U.S. airfares face new pressure as jet fuel costs surge

Your next flight may cost more

If you’ve been checking airfare lately, you may have noticed prices creeping up. That isn’t just your imagination. New pressure is building on ticket prices as jet fuel costs rise.

Fuel is one major driver. Reuters reports that fuel is typically airlines’ second-largest expense after labor, accounting for roughly one-fifth to one-quarter of operating costs.

When fuel prices jump quickly, airlines often try to recover some of the increase by raising fares or offering fewer discounts.

Why fuel suddenly jumped

After U.S. and Israeli strikes on Iran in late February, the conflict quickly reverberated through oil and jet fuel markets, putting airlines under fresh pressure.

Because jet fuel is a major airline expense, even a short-lived spike can ripple into fares and fees. That’s why travelers may see prices change as airlines respond to higher fuel costs and operational disruptions.

One waterway matters a lot

Much of this pressure stems from the Strait of Hormuz. The U.S. Energy Information Administration says oil flow through the strait averaged about 20 million barrels per day in 2024. That represented about one-fifth of global petroleum liquids consumption.

The Strait also matters for natural gas. EIA estimates that around one-fifth of the global liquefied natural gas trade passed through it in 2024. When that route looks less secure, energy markets react very quickly.

Airlines felt it right away

Airlines did not need to wait long to feel the hit. Reuters reported that the Iran war pushed oil prices higher and sent airline shares lower as investors began factoring in higher fuel costs. That kind of market reaction is usually a warning sign for travelers, too.

When airline costs rise suddenly, carriers start looking for places to recover some of that money. Sometimes they do it through fares, sometimes through fewer discounts, and sometimes through both. That is why airfare can start shifting even before travelers fully notice.

United warned changes may come fast

United Airlines CEO Scott Kirby said the effect on ticket prices would likely be felt quickly. He also said higher fuel costs could have a meaningful impact on the airline’s financial results. That is one of the clearest signs yet that carriers are taking the spike seriously.

When a major U.S. airline says fuel is already hitting results, that gets attention across the industry. Other carriers may face the same pressure even if they phrase it differently. For travelers, that can mean less breathing room on price.

Premium seats may move first

Experts told CBS News that airlines had already started raising some fares as spot jet fuel prices climbed. The increases were said to be more noticeable in premium cabins, such as first and business class. Those seats often give airlines more room to test higher pricing.

That does not mean economy fares are safe forever. It just means carriers may try the least price-sensitive seats first. If fuel pressure lasts, cheaper tickets can also start to feel the squeeze.

Basic fares may lag behind

There is one reason airlines may move more carefully on basic economy. Budget-minded travelers are usually quicker to walk away when prices jump. That makes it harder to raise discount fares aggressively all at once.

Airlines are trying to find a balance. Raise fares too much, and demand can soften. Raise them too little, and the fuel spike hurts margins more directly.

U.S. carriers have extra exposure

Reuters reported that U.S. airlines largely stopped hedging fuel over the last two decades. That matters because hedging can cushion the impact of a sudden oil shock. Without it, airlines feel more of the market spike in real time.

Some European and Asian carriers still have more hedging protection in place. That does not make them immune, but it can soften the blow. U.S. airlines generally have less of that buffer right now.

Longer routes add more cost

Fuel prices are not the only issue. Reuters has reported that the conflict has also forced cancellations, diversions, and rerouting across parts of the Middle East. Longer paths mean more fuel burn and more scheduling headaches.

That matters even if your ticket is for a U.S. trip. Airlines operate within a connected global system, and additional operational costs can spread across networks. When disruption grows, it becomes harder to keep fares calm.

Smaller airlines could feel it more

Not every carrier can absorb the same shock. Reuters noted that airlines with lower margins and greater fuel exposure are more sensitive to fuel price increases. That means weaker balance sheets can turn an energy shock into a bigger pricing problem.

Larger airlines may have more flexibility because of stronger revenue and broader networks. Even so, they are not untouched. The question is often not whether they feel the pressure, but how much they can pass on to travelers.

Demand may cushion some of it

There is one reason airfares may not spike evenly across the board. Analysts told Reuters that strong travel demand can offset some of the pain from fuel prices. If planes keep filling up, airlines have more room to manage the shock.

That could create a mixed picture for travelers. Popular routes, holidays, and premium seats may rise faster, while some off-peak fares stay more competitive. So the pressure is real, but it may not hit every booking the same way.

This can feed wider inflation too

Air travel isn’t isolated from the broader economy. Reuters reported that U.S. consumer prices likely rose in February as gasoline prices rose ahead of the Iran conflict, with more inflationary pressure possible if higher energy prices persist.

Higher fuel costs can squeeze travel budgets in multiple ways, from the price of gas to airline operating costs. Mortgage rates have also hovered around the low-6% range in March, keeping housing affordability tight for many buyers.

Not only fuel, but the war is shaking the housing market, too. Check out why mortgage rates are climbing back to 6%.

What travelers may notice next

In the near term, travelers may notice fewer promotions, more limited upgrade deals, or higher last-minute fares before any large move in average ticket-price data.

Business travelers and international flyers may feel changes sooner, while travelers with flexible dates may still find deals. Energy prices remain volatile, and the duration of the Iran war will be a key factor in how long fuel-cost pressure lasts.

Higher gas prices may not fade fast. Check out why Trump now says the Iran conflict could keep fuel costs elevated.
