Gathered in Rio de Janeiro for their annual general meeting, global airline executives confronted a sobering reality: the escalating US-Israel war against Iran is choking jet fuel supplies and disrupting key air corridors, driving costs to levels that threaten a fresh wave of bankruptcies and a rapid consolidation of the industry. “The strong increase in fuel prices, fuelled by the Middle East conflict, is likely to push more airlines into bankruptcy and accelerate consolidation this year and next,” warned the president of the International Air Transport Association (IATA). The conflict has not only squeezed fuel availability but forced costly rerouting, adding to operational pressures at a time when the northern hemisphere’s summer peak is already straining capacity.

The financial pain is rippling outward with geographic precision. Air New Zealand, heavily exposed to Pacific long-haul routes, has managed to hedge only 25 to 40 percent of the fuel impact, its chief executive Nikhil Ravishankar disclosed. Two rounds of fare increases have already been imposed, and “tactical” further hikes are under consideration, with the airline projecting jet fuel at around $150 per barrel through 2027. In Brazil, Azul is responding with capacity cuts rather than price rises. CEO John Rodgerson said the carrier is reducing frequencies to protect cash, and signalled deeper adjustments if the Iran conflict persists. Larger network carriers, he added, are already trimming capacity globally to align with the new cost environment.

Paradoxically, passenger demand is proving stubbornly resilient in key markets. Brazil’s aviation sector registered a record 44.3 million boardings from January to April 2026, a 7.6 percent rise on the previous year, despite higher fares. This demand-capacity mismatch is expected to exert further upward pressure on ticket prices as the industry enters the summer season with fewer available seats.

The strain is also being felt in regulatory arenas and supply chains. IATA’s regional vice-president for the Americas, Peter Cerda, sharply criticised Argentina’s decision to unilaterally raise taxes and fees on air transport without explanation, adding a financial burden that airlines can ill afford. On the manufacturing side, Embraer CEO Francisco Gomes Neto noted a new hesitancy: some airlines are postponing decisions on exercising aircraft purchase options, preferring to wait for greater clarity on the fuel price trajectory. No delivery deferrals have yet been requested, but the caution clouding incremental commitments points to a broader investment chill.

As the Rio summit concluded, the industry’s message was one of managed anxiety. The convergence of structurally higher fuel costs, operational bottlenecks, and geopolitical volatility is reshaping airline economics. While strong post-pandemic demand provides a buffer, the capacity crunch widely predicted for the summer peak risks translating into fewer flights and higher fares for travellers, accelerating the consolidation that many in the sector had hoped to postpone.
