Iran War Cost Brazil’s Airlines US$1 Billion in Extra Fuel
Brazil’s three main airlines absorbed roughly R$5.2 billion (about US$1 billion) in extra fuel costs as the war involving Iran pushed jet-fuel prices sharply higher, according to the industry association ABEAR, a shock that landed on a sector with little financial slack.
A R.2 Billion Rise in Fuel Costs
Brazil’s airlines booked roughly R$5.2 billion (about US$1 billion) in additional fuel costs as a result of the war involving Iran, according to the industry association ABEAR. The figure represents the extra cost of jet fuel attributed to the conflict, not the carriers’ total fuel bill. It falls on three companies — Azul, Gol and LATAM — which between them carry the overwhelming majority of domestic passengers in the country. The episode has been described in industry reporting as the worst crisis the global sector has faced since the COVID-19 pandemic.
That comparison is a heavy one for an industry that spent 2020 largely grounded. What separates the two shocks is the mechanism: COVID-19 destroyed demand, while a fuel spike leaves demand intact and attacks the cost side of the income statement. Airlines can cut capacity in a demand crisis, but in a fuel crisis every flight they continue to operate costs more than it did the week before. Fuel is typically the largest single expense line for a carrier, which is why a price move of this size travels straight to the bottom line.
Why the Strait of Hormuz Sets the Price of a Ticket
The mechanism runs through the Strait of Hormuz, the narrow waterway at the mouth of the Persian Gulf through which a substantial share of the world’s seaborne oil trade passes. Disruption to traffic there does not need to halt shipments to move prices; the risk of interruption is enough to lift crude benchmarks and the freight and insurance costs attached to every cargo. Those increases feed through refineries into the price of every refined product, jet fuel included.
Jet fuel, known in Brazil as QAV, is priced with reference to international quotations, so a carrier in São Paulo pays for a disruption thousands of kilometres away almost immediately. Refining margins on jet fuel can also widen independently of crude when supply chains are stressed, which means the aviation-specific price can rise faster than the oil price itself. For Brazilian airlines there is a second layer, because fuel bought against dollar-linked quotations is paid for out of revenue earned largely in reais.
That combination turns a geopolitical event into an accounting problem. A carrier can hedge part of its exposure, but hedges cover a limited share of consumption for a limited period. When a shock persists beyond the hedging horizon, the protection runs out precisely when it is most needed.
Azul, LATAM and Gol: The Carrier-Level Impact
Azul said it expects a hit of about R$1 billion (about US$200 million) from higher jet fuel prices this year. That is a company-level estimate of the fuel-price effect, disclosed separately from the industry-wide figure compiled by the association. The disclosure matters because it puts a company-specific number on a shock that is otherwise described at industry level, and it covers the full year rather than a single quarter.
LATAM’s published figures sit on a different basis and should not be read alongside the Brazilian total. The carrier estimated a US$40 million hit to first-quarter results and additional fuel expenses of more than US$700 million in the second quarter, but both numbers are group-wide for LATAM Airlines Group across all of its markets rather than for its Brazilian operation. They are therefore not a component of the R$5.2 billion tally compiled by the Brazilian association, which covers Brazil alone. The second-quarter number is also a forward estimate rather than a booked cost, calculated on an assumed average jet-fuel price of about US$170 a barrel.
Gol is the third carrier named in the industry tally, with the association’s aggregate figure serving as the reference point for the sector as a whole. Direct comparisons between the three are complicated by differences in fleet, network and hedging policy, since a carrier flying more long-haul sectors has a different fuel profile from one built around domestic routes. What is common to all three is that the increase arrived as a cost they could neither avoid nor immediately pass on.
A Sector That Was Already Fragile
The shock landed on an industry with little financial slack. Both Gol and Azul have been through Chapter 11 restructuring processes in the United States in recent years, exercises that reduce debt and reset contracts but leave companies with limited room to absorb a new external shock. A fuel surge of this magnitude arriving so soon after those processes tests balance sheets that were rebuilt on the assumption of a calmer input market.
That fragility also constrains the response. A carrier emerging from restructuring has less capacity to absorb losses, fewer options for cheap new financing, and lease and supplier terms negotiated in a different environment. It helps explain why the sector’s reaction has centred on capacity and cost measures rather than on growth, and why the comparison drawn in industry reporting with the pandemic carries weight beyond rhetoric.
How the Airlines Are Responding
Brazilian carriers have responded with capacity adjustments and cost measures. Trimming frequencies, grounding or retiring less efficient aircraft and reworking schedules reduce fuel burn directly, and they are the fastest levers available when the price per litre cannot be controlled. The trade-off is that capacity cuts also remove revenue, so the net benefit depends heavily on which flights are removed.
Hedging and fleet renewal work on longer timescales. Newer aircraft consume less fuel per seat, but delivery schedules are fixed years in advance and cannot be accelerated to meet a crisis. Hedging can smooth the path, but it cannot change the destination if elevated prices persist through the year.
A US$100 Billion Global Bill
The Brazilian figure is one national slice of a worldwide problem. IATA estimates that the war-driven fuel surge will add some US$100 billion to airline costs globally this year, a sum far larger than the profit the industry generates in most years. Because jet fuel is priced internationally, no carrier can opt out of the increase; the only variables are hedging, fleet efficiency and the strength of the markets each airline serves.
That global framing matters for how Brazilian carriers compete. Airlines with stronger balance sheets or revenue in harder currencies can absorb the same percentage increase with less strain, while operators serving price-sensitive domestic markets have less room to recover it through fares. The result is a shock that is uniform in cause but very uneven in consequence.
What It Means for Passengers and Fares
Fuel costs eventually reach ticket prices, but rarely all at once. Airlines typically absorb part of an increase first, because raising prices in a competitive market risks losing volume to rivals. The pass-through tends to show up in reduced availability of the cheapest fare buckets rather than as a headline increase.
Capacity is the other channel passengers notice. When carriers cut frequencies, the remaining seats on a route become more valuable, and average fares drift upward without any formal price change. Route networks can thin out as well, with marginal city pairs among the first to be reviewed when every flight has to justify its fuel bill.
What to Watch Next
The immediate question is duration. If fuel prices ease, the R$5.2 billion becomes a one-off charge against a difficult year; if they hold, it becomes the new planning base, and the capacity and fare adjustments made so far will not be the last. Second-half results from the three carriers will show how much of the cost was absorbed and how much was recovered.
Beyond that, the sector will be watched for signs of structural strain: further capacity reductions, changes to fleet plans, new financing rounds, or arguments over the taxes and charges layered on top of Brazilian jet fuel. Investors will also be looking at how much of the R$5.2 billion the carriers can recover through pricing rather than absorb, since that split determines whether the shock is a bad year or a lasting impairment. The comparison with the pandemic drawn in industry reporting sets a high bar, and the coming quarters will determine whether it was a warning or an accurate description.

Frequently Asked Questions
How much did the Iran war cost Brazil’s airlines?
Brazil’s airlines booked about R$5.2 billion (about US$1 billion) in extra fuel costs because of the war, according to the industry association ABEAR. The figure covers the additional cost of jet fuel attributed to the conflict rather than total fuel spending. It applies to the three carriers named in the tally: Azul, Gol and LATAM. The episode has been described in industry reporting as the worst crisis the global sector has faced since the COVID-19 pandemic.
Why does a conflict near the Strait of Hormuz raise jet fuel prices?
A substantial share of the world’s seaborne oil trade passes through the Strait of Hormuz, so any threat to traffic there affects global crude benchmarks. Higher crude prices, wider refining margins and increased freight and insurance costs all feed into refined products such as jet fuel. Because jet fuel is priced against international quotations, airlines far from the region pay the higher price almost immediately. For Brazilian carriers, the effect is amplified by paying dollar-linked fuel costs out of revenue earned mostly in reais.
Which carriers were affected and by how much?
Azul said it expects a hit of about R$1 billion (about US$200 million) from higher jet fuel prices this year, and Gol is the third carrier covered by the R$5.2 billion industry figure. LATAM has published larger numbers — a US$40 million impact on first-quarter results and more than US$700 million of additional fuel expenses in the second quarter — but those are group-wide for LATAM Airlines Group and are not a component of the Brazilian association’s tally. The second-quarter figure is a forward estimate that assumes an average jet-fuel price of about US$170 a barrel. Direct comparison between the three carriers is difficult because they differ in fleet, network and hedging policy.
Will ticket prices go up?
Higher fuel costs usually reach fares, but with a lag and rarely in full. Carriers tend to absorb part of an increase first, because raising prices in a competitive market risks losing passengers to rivals. The effect often appears as fewer seats sold at the lowest fares, or as higher average prices after frequencies are cut. Brazilian airlines have already responded with capacity adjustments and cost measures.
