What Happened
$1.88. That is how much more US airlines paid per gallon of jet fuel in May 2026 than they did in May 2025 — an 85% single-year jump that pushed the average cost from roughly $2.21 to $4.09 per gallon. Multiply that across the 1.627 billion gallons US carriers consumed in May alone, and the monthly fuel bill lands at $6.66 billion, up 83.9% from $3.62 billion a year earlier, according to Bureau of Transportation Statistics data.
The ignition point was the February 2026 Iran war and the resulting disruptions to the Strait of Hormuz — the narrow passage through which roughly a fifth of global seaborne energy flows. As Nomad Lawyer reported, jet fuel prices vaulted from approximately $85 to over $150 per barrel within weeks, with European jet fuel briefly reaching $1,838 per tonne. IATA's global picture confirms the scale: barrel prices averaged $152 in 2026 versus $90 in 2025, lifting worldwide airline fuel expenditure from $252 billion to $350 billion across the industry.
The same geopolitical shock that sent aviation costs soaring also rattled broader financial markets. As Crypto Newslens documented, the Iran conflict pushed Bitcoin below $62K as investors repriced risk across asset classes simultaneously. Aviation absorbed the blow differently — and, as it turns out, more durably.
The Cost Math: What the Numbers Actually Show
For anyone tracking their personal finance or a diversified investment portfolio (a mix of stocks, bonds, and other assets spread to reduce risk), the significance becomes concrete when you look at fuel's share of total airline operating budgets. Fuel now accounts for 31.4% of airline operating expenses in 2026, up from 25.4% in 2025 — the highest proportion in over a decade, per IATA. Picture a small business whose single largest overhead cost just jumped from one quarter of revenue to nearly one third, with no corresponding revenue windfall to absorb it.
The profitability damage is severe and uneven. IATA halved its global airline profit forecast from $45 billion down to $23 billion for 2026. Middle Eastern carriers swung from a $7.2 billion net profit in 2025 to a projected $4.3 billion net loss in 2026 — a reversal of more than $11 billion in a single year. Meanwhile, US domestic airfares surged 21.6% over just four months between March and June 2026, outpacing international route increases of 11.5%, according to data highlighted by Nomad Lawyer.

American Airlines warned investors of a $4 billion earnings hit and moved to raise baggage fees alongside ticket prices. Return on Invested Capital — ROIC, a measure of how efficiently a company uses investor money to generate profit — dropped across the airline sector to 4.3% in 2026, down from 6.6% in 2025, per IATA. Below the cost of capital for most carriers, that figure signals an industry currently destroying investor value rather than creating it.

Why the Fare Relief You're Waiting For May Never Come
Here is the part that should give every traveler pause: by July 2026, jet fuel prices had already fallen roughly 40% from their April peak, according to the Washington Post. By conventional logic, airfares should have started to ease. They have not — and the people running the airlines are not pretending otherwise.
United Airlines CEO Scott Kirby stated the carrier aims to recover 100% of its fuel costs through ticket prices, warning that fares may rise 15–20% to offset jet fuel expenses. Delta CEO Ed Bastian offered a blunter assessment in earnings calls: Delta is "absorbing probably 50% of the cost on our own and probably 50% will go into pricing," while retaining "any of the pricing strength" even if fuel prices subsequently decline. That final phrase is the tell. This is not a temporary cost pass-through — it is a permanent repricing, framed as a crisis response but intended to outlast the crisis itself.
International fuel surcharges confirm the pattern at the ticket level. Cathay Pacific raised surcharges 34% on top of an earlier 105% increase, while Japan Airlines doubled its North America surcharges to $351 per ticket in the May–June window. Surcharges, once embedded in fare structures, rarely roll back proportionally when underlying costs moderate.
AI-powered dynamic pricing systems compound the stickiness. Airlines increasingly deploy machine learning algorithms that adjust fares in real time based on demand signals, competitive positioning, and even individual browsing behavior. These systems are optimized to maximize yield — which means they are very effective at holding price floors even when the upstream cost driver has eased. For anyone checking fares repeatedly on their phone, the algorithm is aware of the pattern and adjusts accordingly. The same technology that helps fintech travel platforms predict price fluctuations also helps carriers maintain premium pricing longer than traditional yield management models ever could.
The Booking Window: When to Move on Flights
The structural supply picture adds a layer of pressure that neither airlines nor fuel markets can quickly resolve. As of July 9, 2026, the US Energy Information Administration projects US jet fuel days of supply will fall to 21 days in 2026 — the lowest level since 1963. That is not a problem a pricing algorithm can fix. It is a supply-chain constraint that keeps a floor under fuel costs regardless of what happens diplomatically in the Middle East, and it is the kind of number that tends to reappear during the next demand surge.
Middle East carriers have already reduced demand by 11.4% and major carriers canceled routes and cut millions of seats through summer 2026. Fewer seats competing for the same demand is the textbook setup for sustained fare pressure. Given all of that, waiting for a significant fare correction carries real risk. Here are three moves worth considering now.
International airfares rose 11.5% over four months and face continued structural pressure from reduced Middle East carrier capacity. Award redemptions that waive carrier-imposed fuel surcharges — where your frequent flyer points or credit card currency specifically exempts the fuel levy — can meaningfully reduce what you actually pay on long-haul routes. Know before you book whether your points currency passes the surcharge through or absorbs it.
Japan Airlines' $351 North America surcharge and Cathay Pacific's compounding increases are baked into the total ticket price shown at checkout, but they behave differently from base fares in loyalty programs. Some airline and credit card points programs let you redeem at the base fare level, avoiding the surcharge entirely. For a $700 long-haul ticket where $351 is a surcharge, paying cash versus using the right points currency is not a marginal difference — it is a 50% cost swing on the surcharge component alone.
With the industry-wide ROIC at 4.3% — below the cost of capital for most carriers — the airline sector is not currently earning its way. American Airlines' $4 billion earnings hit, the Middle East swing from $7.2 billion in profit to a $4.3 billion projected loss, and IATA's halved global profit forecast of $23 billion all point toward continued earnings pressure through at least the second half of 2026. In a financial planning context, overweighting airlines in a diversified investment portfolio carries sector risk that was not present in 2025.
Frequently Asked Questions
Why are flight prices so high in 2026 if jet fuel costs have already started to fall?
Airlines used the February–April 2026 fuel spike to justify large fare increases, and those prices have proven sticky. Delta's CEO explicitly stated the airline intends to retain its pricing strength even if fuel costs decline — a position corroborated by capacity cuts that reduced available seats and lowered competitive pressure on fares. AI-powered dynamic pricing systems also help carriers hold price floors more effectively than older yield management tools would allow.
How much does jet fuel cost US airlines per gallon in 2026?
As of May 2026, Bureau of Transportation Statistics data shows US airlines paid an average of $4.09 per gallon — up $1.88, or 85%, from the prior year. Prices have likely moderated somewhat since April's peak; the Washington Post reported a roughly 40% decline from that high by July 2026. However, official monthly BTS data through July has not yet been published as of this writing, so the current per-gallon figure should be treated as directional rather than precise.
What is causing jet fuel prices to increase, and will the situation resolve itself?
The primary driver was the February 2026 Iran war and disruptions to the Strait of Hormuz, which sent fuel from roughly $85 to over $150 per barrel within weeks. IATA cited "war-related disruptions in the Middle East and rising fuel costs" as the key factors shifting the industry outlook. A structural issue complicates the picture beyond geopolitics: the EIA projects US jet fuel days of supply will reach their lowest level since 1963 in 2026, meaning inventory buffers are thin even if diplomatic conditions improve.
Are airline ticket prices going to keep rising through the rest of 2026?
IATA's halved profit forecast and airline CEO statements suggest limited near-term fare relief. United Airlines CEO Scott Kirby warned of 15–20% ticket price increases to recover fuel costs. Capacity cuts — millions of seats removed from summer schedules — reduce the supply-side pressure that would otherwise force fares down. Whether fares rise further or plateau at current levels depends heavily on geopolitical developments and whether US jet fuel supply constraints ease in the second half of the year.
- As of May 2026, US airlines spent $6.66 billion on fuel in a single month — 83.9% more than May 2025 — after the February Iran conflict sent jet fuel past $150 per barrel, per BTS data.
- Fuel now accounts for 31.4% of airline operating expenses, the highest share in over a decade, and IATA cut global industry profit forecasts in half to $23 billion for 2026.
- Fares have not followed fuel prices back down: airline CEOs have publicly stated they plan to retain elevated pricing even as fuel moderates, and AI-powered yield management systems help them hold that floor more effectively than ever before.
- For both travelers and investors, the signals point in the same direction — act now rather than waiting for a correction that the airlines themselves have said they are not planning to deliver.
In my analysis, the most underreported element in this story is not the fuel cost itself — it is the frank acknowledgment from major airline CEOs that they intend to permanently capture the pricing headroom created by a temporary cost spike. When I review Ed Bastian's statement about retaining "any of the pricing strength" alongside IATA's halved profit forecast, the picture is not of an industry transparently passing costs to consumers while planning to pass savings back. It is an industry that found a durable pricing reset hiding inside a crisis, and is being unusually candid about keeping it.
