Soaring aviation fuel prices push airlines into 'self-preservation mode,' prompting intensified flight cancellations ahead of the summer peak season.

According to aviation data analytics firm Cirium, global airline capacity in May has already been reduced by approximately 3 percentage points; among the world’s top 20 carriers, only one has refrained from cutting flights. Cirium has downgraded its full-year capacity growth forecast—from an earlier projection of 4%–6% growth—to a revised outlook of "potentially declining by 3% under specific conditions." This crisis initially affected only Middle Eastern carriers and their airspace, but rapidly spread globally after the U.S. Navy blockaded the Strait of Hormuz, halting Iranian oil exports. KLM Royal Dutch Airlines announced on Thursday that it would cancel 80 round-trip flights from Amsterdam Schiphol Airport over the next month—joining United Airlines, Lufthansa, and Cathay Pacific in scaling back operations. Richard Evans, Senior Advisor at Cirium, stated bluntly in his report: "Further cuts are virtually inevitable." Airlines across all regions—from North America and Europe to Asia-Pacific—are retrenching. U.S. carriers face the most direct impact. United Airlines is cutting capacity by 5% for the full year, with reductions extending through September. Delta Air Lines expects to absorb an additional $2.5 billion in fuel costs this quarter, offsetting them via fare hikes and a roughly 3.5% reduction in capacity. Delta CEO Ed Bastian remarked: "Any route operating at the margin—or failing to meet revenue expectations—will be subject to re-evaluation. This will be a test for the entire industry." Lufthansa took the most aggressive action this week. Europe’s largest airline, facing mounting pressure from both labor strikes and soaring fuel costs, has shut down its regional subsidiary CityLine, grounded 27 CRJ regional jets, and retired some aging Boeing 747s and Airbus A340 wide-body aircraft. Group CFO Till Streichert stated: "Given the sharp rise in aviation fuel costs and persistent geopolitical instability, accelerating fleet and capacity adjustments is unavoidable." Its Edelweiss brand has also suspended services to Denver and Seattle. Pressure is mounting across the Asia-Pacific region as well. Qantas has cut domestic capacity by 5% through end-June, reduced flights to the U.S., and anticipates an additional ~AUD 800 million (USD 575 million) in fuel expenses for the second half of its fiscal year. Cathay Pacific will reduce flight frequency across Asia-Pacific by 2% from mid-May through end-June; its low-cost subsidiary HK Express plans cuts of up to 6%.

Skyrocketing fuel prices are eroding domestic airlines’ profitability.

For example, China Southern Airlines’ aviation fuel expenditure reached RMB 52.526 billion. Assuming unchanged fuel consumption, a 10% increase in procurement price would add approximately RMB 5.2 billion to its annual fuel cost. Many routes were already operating on razor-thin margins; even a modest fuel price fluctuation can completely flip the color of the bottom line. Older aircraft suffer disproportionately: flying just a few extra hours quickly magnifies cost differentials—even if load factors look impressive, a full cabin may still yield little profit once fuel procurement costs are factored in. More critically, passengers remain oblivious to airlines’ complex cost calculations. Numerous popular domestic routes overlap heavily with high-speed rail networks. Even a slight fare increase prompts travelers to open their booking apps and seamlessly switch to rail—recent fare hikes have already begun dampening demand, with short-haul passengers increasingly opting for trains. To retain passengers, airlines naturally prioritize deploying capacity on trunk routes with relatively stable business demand—such as Beijing–Shanghai, Beijing–Guangzhou, and Shanghai–Shenzhen. Yet when everyone concentrates capacity on these same corridors, seat supply surges rapidly. Although summer flights appear full, no carrier dares fully pass on skyrocketing fuel costs to ticket prices. Behind the recent three consecutive reductions in fuel surcharges lies airlines’ grim determination to absorb losses rather than risk pushing more passengers toward high-speed rail. Costs that cannot be passed on must instead be clawed back from seats, meals, and service offerings. 03 Airlines naturally hope someone else will absorb soaring fuel costs—but consumers’ wallets are equally strained. In the first half of this year, China’s national retail sales of consumer goods grew by only 1.3%, down sharply from 5.0% year-on-year in the same period last year. While markets remain open, consumers are demonstrably more cautious in spending. Even amid tourism’s apparent vibrancy, similar shifts are underway. During the May Day holiday, domestic travel volume rose 3.6% year-on-year, yet average per-capita spending dipped slightly—from approximately RMB 574 last year to RMB 571 this year. Though travelers remain on the move, the economic value per trip is quietly contracting. Hotel owners worry about where guests will come from; travel agencies receive many inquiries but face repeated haggling before final bookings materialize. For airlines, squeezed simultaneously on both the consumer-demand and cost sides, capacity control appears to be the only viable lever for 2026. Air China reduced domestic passenger capacity by 7.7% in June, resulting in a 6.7% decline in passenger-kilometers flown—yet load factor rose by 0.9 percentage points. Superficially, each flight carries more passengers, while poorly performing services have simply vanished from schedules. Perhaps flying fewer flights helps the company’s financial statements—but for employees, it soon translates directly into numbers on their pay slips. Due to…

Lufthansa Braces for Jet Fuel Crunch, Higher Costs May Force Fleet Cuts
