Airline Leaders Head to Rio Confronting Fuel Shock from Iran War

IATA summit to weigh surging jet fuel costs, airspace disruption and fleet constraints as carriers reassess routes and fares

By Sofia Navarro BA EZJ

Executives and industry stakeholders gathering for the International Air Transport Association annual meeting in Rio de Janeiro will confront a sharp rise in jet fuel prices, flight detours tied to the Iran war and growing delivery and engine shortages. The disruptions are squeezing margins, prompting fare increases, route cuts and a reassessment of carriers' ability to meet climate targets amid constrained sustainable aviation fuel supplies.

Key Points

  • IATA summit in Rio will focus on rising jet fuel costs, airspace disruptions from the Iran war, aircraft and engine delivery delays, and implications for profitability and climate targets.
  • Carriers have responded with fare increases, route cuts and cash conservation; the ability to recover higher fuel costs varies by market and business model, affecting airlines, aircraft manufacturers and fuel suppliers.
  • Moody’s downgraded the global airline sector outlook to negative, forecasting substantial profit declines into 2026; passenger traffic contracted in April, led by Middle Eastern carriers.

RIO DE JANEIRO, June 4 - Airline executives from around the globe will convene in Rio de Janeiro from June 6-8 for the International Air Transport Association (IATA) annual meeting at a moment of acute industry stress. Deliberations will focus on a cascading set of pressures triggered by the Iran war - notably higher jet fuel costs and restricted Middle Eastern airspace - that are forcing longer routings, raising operating expenses and testing carriers' pricing power.

IATA represents more than 370 airlines that account for roughly 85% of global air traffic, making the summit the industry’s largest forum for carriers, manufacturers, suppliers and financiers. Before the Iran war, the aviation sector had been projected to post record profits of $41 billion this year; industry executives and analysts expect that forecast to be downgraded during the meeting as the conflict's effects ripple through operating models.

Discussion at the summit is expected to center on several interlinked topics: surging fuel prices and fears over supply, disruptions to Middle Eastern airspace, worsening aircraft and engine delivery delays, and the mounting difficulty of meeting climate commitments, particularly the IATA goal of net-zero emissions by 2050 amid high costs and limited availability of sustainable aviation fuel.


Market and operational responses

Airlines have begun responding to the shock with a combination of fare increases, the pruning of unprofitable services and tighter cash management. Those measures are uneven in their effectiveness because carriers vary in demand strength and exposure to premium traffic. For some airlines, particularly those with robust premium demand, fare increases are easier to implement without materially weakening load factors. For others, competitive dynamics and constrained consumer ability to absorb higher fares limit pass-through.

Southwest Airlines CEO Bob Jordan, whose carrier joined IATA last year, said U.S. airlines had raised fares seven times since February without seeing a decline in demand, but added that current fares were still "not close" to covering prevailing fuel costs. Air India's outgoing chief executive Campbell Wilson highlighted that higher fuel prices and airspace closures were making certain routes uneconomic: "When you take on all those competitive dynamics, the added cost of this extra flying, the added cost to fuel, it just makes some routes uneconomic," he said.


Regional impacts and route dynamics

Gulf carriers face a specific test given their hub-centric models in Dubai, Doha and Abu Dhabi. While the Iran war has not ended the Gulf hub system, detours have exposed the model's dependence on available airspace and established routings. Longer flights have increased fuel burn and flight times. Some European and Asian carriers, including Lufthansa Group, Air France-KLM, Singapore Airlines and Cathay Pacific, are finding opportunities on certain long-haul flows by operating non-stop services that avoid the most disrupted airspace.

For European carriers, the situation is mixed: they may gain incremental demand on some long-haul corridors, but continue to face headwinds from higher fuel bills, closed Russian airspace, air traffic control disruptions and mandates for sustainable aviation fuel. In Asia, Air India is dealing with higher fuel costs and lengthened routings, while IndiGo remains exposed to aircraft shortages and to Pratt & Whitney engine problems. Japanese carriers confront amplified fuel costs due to currency weakness, and Air New Zealand has warned of a sharp earnings impact.

In Latin America, the fuel shock collides with currency swings and constrained consumer purchasing power, limiting the ability to pass on costs through higher fares. LATAM has already reduced its earnings forecast because of elevated fuel costs, and Brazil’s Azul remains exposed to fuel price and currency volatility.


Traffic, profits and rating outlooks

IATA data showed global passenger traffic contracted in April for the first time since the post-pandemic recovery, a decline led by Middle Eastern carriers. Credit watcher Moody’s Ratings last week lowered its outlook for the global airline sector from stable to negative, citing fuel costs tied to the Iran war and disruptions near the Strait of Hormuz that would "materially reduce" operating profit this year. Moody’s said profits could fall by more than 35% in 2026 before a potential recovery the following year.


Fleet and supply constraints

Compounding the fuel shock are delivery delays and engine shortages. Delays from Boeing and Airbus are keeping older, less fuel-efficient aircraft in service, further pressuring margins. United Airlines CEO Scott Kirby estimated at a recent conference that 800 to 900 aircraft worldwide were grounded because of engine issues, saying: "There are not enough engines and they’re not going to be for many, many years." The shortage of engines and components has become a constraining factor for capacity growth.


Industry consolidation and dealmaking

The cost shock is reviving discussion of consolidation as carriers with thinner margins and less pricing power struggle. The recent collapse of U.S. low-cost carrier Spirit Airlines underlines the fragility of weaker players. Investment firm Castlelake, an aircraft lessor and investor in Scandinavia’s SAS, has signaled it is considering a possible offer for easyJet, while United's informal outreach to American Airlines has again put potential U.S. deal activity in focus - despite American rejecting that approach and signals from regulators in Washington that they may be resistant to consolidation.


Outlook and constraints on climate goals

One of the summit's central tensions will be balancing short-term financial survival with longer-term environmental commitments. Airlines are already conserving cash and prioritizing operational resilience - actions that can reduce their capacity to invest in sustainable aviation fuel and other decarbonization pathways. Given the high cost and limited supply of sustainable aviation fuel, industry participants will be debating how feasible the IATA net-zero by 2050 target remains under current economic pressures.

The Rio meeting will bring together hundreds of executives, manufacturers, suppliers and financiers to debate these issues and potentially revise industry profit outlooks in light of the Iran war's ongoing disruptions.

Risks

  • Higher fuel prices and disrupted Middle Eastern airspace could materially reduce airline operating profits and lead to route cancellations - impacting airline revenues and jet fuel suppliers.
  • Aircraft and engine shortages, and delayed deliveries from major manufacturers, are forcing continued use of older, less efficient jets and limiting capacity - affecting fleet planning and lessors.
  • Limited supply and high cost of sustainable aviation fuel complicate carriers’ ability to meet IATA’s net-zero by 2050 target while also absorbing near-term financial pressures - affecting decarbonization efforts in aviation.
