How the Iran War Fuel Shock Is Reshaping Global Aviation in 2026

The Gulf Divide: Emirates’ Sprint and Qatar’s Climb

The Iran war did not hit all Gulf carriers equally, and their recovery paths expose a stark divergence in resilience.

Emirates has mounted the fastest comeback. By May 4, 2026, the Dubai-based carrier had restored 96% of its global network, serving 137 destinations across 72 countries . This was a remarkable feat considering that in early March the airline was operating at just 60% of pre-war capacity . However, the recovery proved fragile. In a significant reversal, Emirates removed nearly 500,000 seats from its June 2026 schedule, cutting capacity by roughly 16% year-over-year and reducing daily outbound flights from 237 to 200 as airspace closures linked to the ongoing conflict continued to disrupt routes .

Qatar Airways faced a far deeper crisis. At its lowest point on March 28, 2026, the carrier was operating at just 20% of its pre-war capacity from Doha, with flight tracking data showing only 40 daily departures — one-fifth of normal operations . The airline has since been ramping up steadily, operating 130 daily departing flights by April 17, which represents a 65% increase from early April but still only about 60% of pre-war levels . The damage is evident in its financials: Qatar Airways reported a 7.1% decline in annual net profit as it works to rebuild its global schedule in what its CEO described as the industry's most severe operational crisis since the COVID-19 pandemic .

The contrasting trajectories mean Emirates rebounded faster but is now cutting capacity, while Qatar Airways is climbing from a much deeper trough with significant structural headwinds still in place .

Executive Warnings: Profits, Surcharges, and a New Cost Reality

Across the industry, senior executives are delivering stark warnings. The common thread is that fuel costs have structurally reset higher, and no one expects a quick return to normal.

IAG: A €2 Billion Fuel Shock

The parent company of British Airways and Iberia now expects its 2026 fuel bill to reach €9 billion — a €2 billion increase from its February estimate . CEO Luis Gallego stated that higher fuel prices would “inevitably lead to lower profit this year than we originally anticipated” . IAG has hedged approximately 70% of its fuel needs, but still expects to recover only about 60% of the cost increase through revenue actions, with stronger pass-through in long-haul and premium markets . The group is curbing its supply growth plans, cutting its second-quarter capacity increase to just 1% and its third-quarter target to 2% .

IATA: Profits Halved Across the Industry

The global picture is grim. IATA forecasts that airline industry profits will halve to $23 billion in 2026, down from $45 billion in 2025 . Director General Willie Walsh described the situation as a “perfect storm,” noting that all airline profits are “suffering” from the rapid rise in fuel costs .

Air France-KLM: A Deepening Capacity Cut

The Franco-Dutch group slashed its 2026 capacity growth outlook from 3–5% to 2–4% . It warned of a €940 million ($1.1 billion) fuel shock in the second quarter alone, with jet fuel prices in northwest Europe reaching a record $1,840 per metric ton on April 3, 2026 . Total additional fuel costs for the full year are estimated at €2.4 billion ($2.8 billion), and CEO Benjamin Smith has cautioned that the group cannot fully offset these costs through price increases .

Cathay Pacific: Doubling Down on Surcharges

Hong Kong's flagship carrier faced a doubling of jet fuel prices in March compared to the January–February average due to the Iran war . It responded aggressively, first doubling its fuel surcharges on most routes in March, and then raising them by another 34% in April — adding an extra HK$600 or more for long-haul journeys to Europe and North America . CEO Ronald Lam has stated that the airline's 10% passenger capacity growth plan for 2026 could change if fuel prices stay elevated, adding that capacity cuts remain “a last resort” . Chairman Patrick Healy has separately flagged higher surcharges and ongoing supply chain disruptions as persistent headwinds .

The Competitive Outlook

The market is now shaped by a new cost reality. European and Asian carriers are hiking surcharges and trimming capacity growth, while Gulf carriers are navigating a two-speed recovery. Emirates proved it could rebuild quickly but has now pulled back June capacity, while Qatar Airways is steadily climbing from a much deeper operational hole. The fuel shock has reset the industry's cost base, and the warnings from every major executive point in the same direction: ticket prices will rise, profits will fall, and the full impact of this crisis has only just begun to manifest.
