They will distribute it to the population.
On the first day of April, Petrobras raised jet fuel prices by 55 percent, sending a tremor through Brazil's aviation sector and forcing a reckoning with how fragile the economics of flight truly are. Fuel, which consumes nearly half of what airlines spend to operate, does not absorb shocks quietly — it transmits them, directly and swiftly, into the price of a ticket and the viability of a route. The Brazilian government now stands at a familiar crossroads: intervene to protect connectivity, or allow market forces to quietly sever the aerial threads that bind the country's interior to its center.
- A 55% fuel price hike landed on April 1st with no warning cushion, threatening to push airfares up by as much as 20% across the country.
- Carriers like Azul and Gol, freshly restructured and financially disciplined, have made clear they will not absorb the cost — passengers will.
- The most exposed are Brazil's regional routes, where thin occupancy margins mean a price shock can quickly make a flight economically indefensible.
- Brasília is racing to respond with a two-pronged strategy: zeroing out PIS/Cofins taxes on jet fuel and negotiating a six-month phase-in of the remaining price increase.
- The outcome will determine whether Brazil's expanding regional aviation network continues to grow — or quietly begins to contract.
On April 1st, Petrobras raised jet fuel prices by an average of 55 percent, delivering an abrupt and consequential blow to an aviation industry already operating on tight margins. The federal government moved quickly to explore countermeasures, with the elimination of PIS and Cofins taxes on aviation fuel emerging as the most immediate option on the table.
The numbers are unforgiving. Jet fuel accounts for roughly 40 percent of airline operating costs, meaning a 55 percent price increase is not an abstraction — it is a structural threat. Analysts estimate that without relief, ticket prices could climb by as much as 20 percent. Hugo Queiroz of L4Capital was direct: airlines like Azul and Gol, having recently restructured their finances, are not positioned to absorb this kind of volatility. The cost will move to passengers.
The sharpest danger lies in Brazil's regional routes — the less-traveled corridors connecting smaller cities to major hubs. These routes operate with lower occupancy rates and thinner economic tolerances. A significant fare increase could collapse demand on marginal routes first, leading carriers to reduce frequency or abandon service altogether, quietly unwinding years of regional expansion.
The government's response is taking shape around two levers: immediate tax relief to soften the impact on fares, and a negotiated phase-in that would spread the remaining price increase across six months, protecting airline cash flow and sustaining investment in new aircraft. Queiroz acknowledged that Petrobras followed its own pricing rules in making the adjustment, but noted that technical soundness does not change who ultimately pays. The question now is whether a carefully structured intervention can keep Brazil's regional aviation network intact.
On April 1st, Petrobras raised the price of jet fuel by an average of 55 percent. The move was sudden and substantial, and it landed in an industry already watching its margins closely. Brazil's federal government, recognizing the potential shock to the aviation sector, began exploring immediate countermeasures—chief among them the possibility of eliminating PIS and Cofins taxes on the fuel itself, a move designed to cushion the blow to ticket prices.
Jet fuel is not a minor line item for airlines. It accounts for roughly 40 percent of their operating costs, which means a 55 percent jump in fuel prices translates into a serious problem. Without intervention, analysts estimate that ticket prices could rise by as much as 20 percent. That is not a rounding error. That is the difference between a trip people take and a trip they skip.
Hugo Queiroz, who oversees investment strategy at L4Capital, laid out the arithmetic plainly: airlines will not absorb this cost themselves. They cannot. Companies like Azul and Gol have recently restructured their finances and balance sheets, and they are in no mood to eat volatility the way carriers might have done a decade ago. The money has to go somewhere, and that somewhere is the price of a ticket. "The airlines, after this recent movement, are not going to carry this alone," Queiroz said. "They will distribute it to the population."
But the real damage, if the full price increase is passed through without relief, will likely concentrate on regional routes—the smaller cities, the less-traveled corridors, the flights that operate with lower seat occupancy rates. These routes are the connective tissue of Brazil's interior, linking smaller population centers to major hubs. They are also the most vulnerable to price shocks. When ticket prices rise sharply, demand on marginal routes collapses first. Airlines will cut service, reduce frequency, or abandon routes altogether. The growth that regional carriers have been building will stall.
The government is working on a two-part response. The first is the tax relief—zeroing out PIS and Cofins on jet fuel to reduce the immediate impact on fares. The second is a negotiated phase-in: fuel distributors would pass along only a portion of the price increase immediately, with the remainder spread across six months. The goal is to preserve airline cash flow, keep them investing in new aircraft, and prevent a sudden contraction in route expansion.
Queiroz assessed Petrobras's pricing approach as technically sound. The company, he noted, has been following its established rules, making adjustments for market volatility while maintaining its international parity pricing model. The structure benefits the state while also protecting private investors and shareholders. But structure and soundness do not change the fact that someone pays. The question now is whether the government's tax relief and phased pricing can distribute that cost in a way that does not hollow out Brazil's regional aviation network.

La Conversación del Hearth Otra perspectiva de la historia
Why does a 55 percent fuel price increase matter so much more to regional airlines than to the big carriers?
Regional routes operate on thinner margins. A flight from São Paulo to Rio can fill most of its seats. A flight from São Paulo to a smaller city in the interior might be half full. When fuel costs spike, that half-full flight becomes unprofitable. The big carriers can absorb it across their network. Regional operators cannot.
So the government's tax relief—eliminating PIS and Cofins—that actually helps?
It helps, but it is not a complete fix. It reduces the shock, buys time. But if fuel costs stay elevated, you are still looking at higher ticket prices. The phased approach—spreading the increase over six months instead of all at once—is really about giving airlines breathing room to adjust without cutting routes immediately.
What happens if they do cut regional routes?
You lose connectivity. Smaller cities become harder to reach. People drive instead of fly, or they don't travel at all. Economic activity slows. It is not dramatic, but it is real.
Is Petrobras doing something wrong here?
Not necessarily. They are following their pricing rules, which are tied to international markets. The problem is that the rule itself—parity pricing—means Brazilian airlines absorb global fuel volatility. That is a structural issue, not a Petrobras mistake.
So what is the real risk?
That airlines, especially the ones that have just cleaned up their finances, decide regional routes are not worth the trouble anymore. You get a network that serves only the profitable corridors. The interior gets left behind.
