The oil shock is not fading from the headlines and is leaving red ink on airline balance sheets

At first glance, aviation is beginning to look remarkably normal again. Global scheduled seat capacity reached 137.1 million in the week to 21-Sep-2026, 1.6% above a year earlier, while outside the Middle East capacity and traffic are broadly reverting to familiar seasonal patterns.

Yet the industry's underlying economics are moving in the opposite direction. Jet fuel has climbed back towards USD200/bbl, with the average price reaching USD194.90/bbl in the week to 18-Sep-2026 - 116.4% above a year earlier - while the fuel crack spread was up 219.2%.

The latest issue of CAPA - Centre for Aviation's Airline Leader Briefing points to an aviation market caught between resilient demand and deteriorating cost conditions.

International tourist arrivals were broadly flat in 1H2026, large aircraft deliveries are finally accelerating and several markets continue to grow. But airline financial results are weakening, consumer behaviour is becoming more price-conscious and the oil market has become increasingly difficult to forecast.

The central question is no longer whether aviation can operate through the crisis. It can. The question is how much financial damage is accumulating beneath that operational resilience - and whether airlines enter 2027 with materially weaker balance sheets just as the next phase of the cycle begins.

Summary

• Global airline capacity looks “normal” again, reaching 137.1 million weekly seats (+1.6% YoY) with seasonal patterns reasserting outside the Middle East.
• Jet fuel has surged back near USD200/bbl (USD194.90/bbl, +116% YoY) and crack spreads are sharply higher, undermining airline cost predictability.
• Geopolitics has become the top industry risk, driving disruption across fuel, routing, insurance, corporate travel policies, and booking behaviour.
• Demand is resilient but increasingly K-shaped, with higher-income travellers sustaining travel spend while lower-income segments become more price-sensitive and selective.
• Cargo and trade flows are re-routing (e.g., weaker Asia-Europe, stronger transpacific and Southeast Asia-US lanes), making network assumptions less reliable.
• Aircraft deliveries are accelerating just as airline finances weaken, contributing to a two-speed industry where stronger carriers keep investing while weaker ones face restructurings and balance-sheet strain into 2027.

Aviation is starting to look normal again

The most misleading feature of the current market is how normal it looks from a distance. Global scheduled airline capacity reached 137.1 million seats in the week to 21-Sep-2026, up 1.6% year-on-year and 401,000 seats week-on-week. Capacity is 0.8% higher year-to-date.

Seasonal patterns are beginning to reassert themselves: Asia Pacific is building around autumn holidays, the Americas are moving through a seasonal upswing, Latin America is beginning its traditional end-of-year expansion and European capacity is easing after the summer peak.

This is not what a global aviation recession looks like. Nor is it an industry behaving as though passengers have stopped travelling.

UN Tourism recorded approximately 690 million international arrivals in 1H2026, 0.4% above 1H2025. Even after a 1% decline in 2Q2026, expectations for the second half have become mildly more positive: 39% of experts surveyed expected tourism prospects to improve, against 31% expecting deterioration.

The problem is that operating normality and economic normality are no longer moving together.

The oil market has become aviation's black box

The industry's greatest uncertainty is now sitting outside the airline timetable.

The IEA has cut its 2026 global oil demand forecast by 940,000 bpd and now expects demand to fall by an average 2.5 million bpd, while increasing its estimate of supply losses from 4.4 million to 5.7 million bpd. More than 10 million bpd of Gulf production remains shut in, with regional crude exports in Aug-2026 at only around 55% of pre-conflict levels. Global observed oil inventories have fallen by 507 million barrels since Feb-2026.

That combination makes conventional forecasting unusually fragile.

Jet fuel prices rose 7.4% week-on-week to USD194.90/bbl in the week to 18-Sep-2026. They were 116.4% higher than a year earlier, while the crack spread was 219.2% higher. Crude prices had risen more than 12% week-on-week as inventories fell, refinery throughput weakened and renewed military activity threatened critical shipping routes.

The significance for airlines is not simply that fuel is expensive. It is that the industry's ability to establish a reliable cost assumption is deteriorating.

J.P. Morgan's admission that it "doesn't have a baseline view" and does not know "how to model the endgame" is unusually revealing.

For airline planners, uncertainty itself has become a cost.

Geopolitics has overtaken demand as the industry's defining risk

Sabre and Cantor Fitzgerald's 'Navigating the Fog' survey of travel executives found geopolitical instability to be the industry's leading concern, ahead of consumer price inflation, sustained business cost pressures, weakening economic growth and declining consumer confidence. Airlines were regarded as particularly vulnerable because disruption affects both networks and corporate travel policies.

This is significant because the industry's risk hierarchy has changed. Before the conflict, airlines could largely treat geopolitical disruption as an episodic operational variable. Now it increasingly determines fuel, insurance, routing, capacity allocation, consumer sentiment and corporate travel behaviour simultaneously.

Travellers have not abandoned travel, but they are spending more time searching for value. That is lengthening the period between initial travel research and booking, while suppliers hold inventory for longer.

For airlines, this introduces another form of uncertainty. A strong booking curve can no longer be assumed simply because demand exists. Consumers are shopping harder before committing.

The revenue management challenge therefore becomes less about filling aircraft and more about determining where genuine willingness to pay exists.

The passenger is still travelling - but increasingly on two different balance sheets

The emerging consumer picture is distinctly K-shaped.

Future Partners' Aug/Sep-2026 US traveller survey found that 52.3% of respondents experiencing deteriorating financial sentiment said this was reducing current spending intentions, particularly among lower-income consumers. Yet travel intentions remained broadly stable. Among the highest-income group, 75.8% considered leisure travel a high spending priority, compared with 41.3% among the lowest-income group.

This helps explain why airlines can raise fares and still maintain relatively healthy demand.

The passenger base is not responding uniformly to inflation. Higher-income travellers are protecting travel expenditure more effectively, while price-sensitive consumers are becoming more selective.

A market can retain demand while losing its most price-sensitive passengers, leaving airlines with a superficially resilient load factor but a fundamentally different customer mix.

Asia Pacific illustrates the point. International passenger traffic for regional airlines fell 1.3% in Jul-2026, with higher fares and network rationalisation particularly affecting short-haul and price-sensitive leisure markets. Yet RPKs increased 1.1%, supported by encouraging long-haul performance.

The passenger has not disappeared. The low-yield passenger is becoming harder to retain.

Freight is following the same geographical logic

Air cargo provides an early indication of how the global economy is adapting rather than simply contracting.

DHL reported global air cargo volumes up 5% year-on-year in Jul-2026, with capacity rising only 1%. Asia Pacific led growth at 7%, followed by Latin America at 3%, North America at 2% and Europe at 3%. But Asia-Europe traffic fell 7%, while Middle East-Europe traffic fell 9%.

The interesting development is not the aggregate growth rate but the re-routing of trade.

Freighter capacity from Asia Pacific is shifting away from Europe towards the transpacific market following changes to EU e-commerce rules. Meanwhile, China-US freight's share of global traffic fell from 34% to 28% in the first seven months of 2026, while other Asian markets surged: Vietnam-US traffic increased 35.9%, Thailand-US 26.5%, India-US 23.4%, South Korea-US 20.2% and Taiwan-US 17.0%.

The air cargo market is therefore demonstrating a wider economic truth: globalisation is not disappearing, but its geography is becoming more fluid. For airlines, that creates opportunities in the right markets - but also makes yesterday's network assumptions less reliable.

Aircraft supply is finally improving, just as airlines become more cautious

There is a striking timing problem in the fleet market.

Airbus and Boeing delivered 877 commercial aircraft in the first eight months of 2026, 70 more than in the same period of 2025. Airbus deliveries rose to 475, while Boeing increased to 403. Boeing's 737 MAX deliveries rose from 285 to 320, while Airbus increased A320neo family deliveries from 333 to 369.

That is meaningful progress after years in which supply-chain constraints prevented airlines from receiving aircraft at the rate they had planned. But the improved supply pipeline is arriving into a market in which the value of additional capacity is increasingly dependent on fuel economics.

Boeing is targeting a stable 737 MAX production rate of 47 aircraft per month, despite constraints in wing production, while Airbus is targeting around 870 deliveries in 2026.

This could become a double-edged development. More aircraft allow airlines to replace inefficient older fleets and protect network growth. But they also create capital commitments at precisely the moment when cash preservation is becoming more important.

Aircraft availability is improving. The question is whether the economic environment will allow airlines to deploy that capacity profitably.

Middle East recovery is real - but incomplete

The Middle East has moved beyond the acute operational phase of the crisis, but it has not returned to normal.

Regional scheduled capacity stood at 8.0 million seats in the week to 21-Sep-2026, down 7.4% year-on-year and broadly aligned with 2024 levels. Delays and cancellations remain above historical norms, while airlines continue to reroute some services because of the security environment.

There has nevertheless been substantial recovery. flydubai had restored 85% of its network by mid-Sep-2026, while South Asian, European and North American airlines were progressively restoring services.

The more revealing weakness is among LCCs. Overall regional capacity has recovered to 94% of its 2025 level, but LCC capacity has recovered only 88%, leaving approximately 600,000-650,000 weekly two-way seats absent from the market.

That is not a trivial gap. It indicates that the recovery is strongest where demand is either strategically important or relatively less price-sensitive, while lower-margin traffic remains more difficult to restore.

This supports CAPA -Centre for Aviation's assessment that full Middle East recovery is unlikely until well into 1Q2027.

The real damage is appearing in airline balance sheets

This is where the narrative becomes materially less comfortable.

The second-quarter financial results are increasingly showing the lagged impact of the crisis. Airlines have absorbed higher fuel costs, disruption and weaker yields in different combinations, but the cumulative effect is becoming visible in profitability.

airBaltic's voluntary Chapter 11 filing on 14-Sep-2026 is an extreme example rather than evidence of a universal industry problem. Yet its significance lies precisely in that distinction. The airline had secured EUR350 million in debtor-in-possession financing, following a EUR257 million financing arrangement announced earlier in Sep-2026.

For financially marginal airlines, a prolonged period of extreme fuel costs does not need to destroy demand to become existential.

The contrast with stronger carriers is becoming increasingly stark. North American airlines are pruning less profitable flying while expanding premium seating and ancillary revenues. European operators such as Aegean Airlines are explicitly committing to disciplined capacity while continuing fleet and network investment.

The industry is therefore splitting.

Carriers with balance-sheet strength, premium exposure, pricing power and relatively favourable fuel economics can absorb the shock and continue investing. Those without those characteristics are being forced into defensive decisions that can weaken their competitive position just as the market eventually improves.

The next stage of the crisis may be less visible than the first

The most consequential change is therefore not another capacity cut or another spike in oil. It is the possibility that airlines enter 2027 with less financial resilience than they had at the start of 2026.

The industry's operational response has been comparatively effective. Capacity outside the Middle East has broadly returned to seasonal patterns. Global seats are still growing. Demand remains resilient. Aircraft deliveries are accelerating.

But those indicators describe the industry's ability to operate, not its ability to generate returns.

The distinction becomes critical if oil remains elevated. Airlines can withstand an isolated fuel spike through hedging, fare increases, network adjustments and capacity discipline. They are far less equipped to absorb a prolonged period in which fuel prices remain close to USD200/bbl, crack spreads stay elevated and consumers become progressively more selective.

The current market is therefore producing an unusual combination: healthy enough demand to prevent a collapse, but sufficiently high costs to erode the economics of marginal capacity.

That is why the next stage of the crisis may be less visible than the first. There may be fewer cancellations and fewer closed airspace corridors. Instead, the effects will appear in deferred fleet investment, slower network growth, weaker balance sheets, higher fares, airline restructurings and a widening gap between financially strong and financially vulnerable carriers.

The industry's operating recovery is already underway, but its economic recovery has not yet begun.

CAPA Perspective: The industry's recovery is becoming increasingly two-speed

The latest evidence points to an aviation industry that has become operationally resilient but economically fragile.

The Middle East is no longer experiencing the wholesale network disruption seen during the acute phases of the conflict. Capacity has stabilised, airlines are restoring routes and most markets outside the region are behaving seasonally again.

Yet Middle Eastern capacity remains 7.4% below 2025 levels and LCC recovery is materially further behind. Full recovery is unlikely until well into 1Q2027.

Elsewhere, the industry's resilience is clearer. Demand remains sufficiently strong for airlines to raise fares and retain traffic, particularly in higher-income and less price-sensitive markets. Capacity is still growing. Aircraft deliveries are accelerating.

But this should not be interpreted as evidence that the crisis has passed.

The economic damage is still accumulating. Jet fuel approaching USD200/bbl, depleted oil inventories and continuing uncertainty over the conflict's endgame mean that airline cost assumptions remain unusually unstable.

That is producing a two-speed industry. Airlines with strong balance sheets, premium demand, pricing power and lower relative fuel exposure can protect networks and continue investing. Carriers operating in more price-sensitive markets, with higher fuel exposure or limited financial headroom, face a much more difficult proposition.

The danger is that this divergence becomes permanent.

If the oil shock persists, 2027 could begin with aviation demand intact but an industry financially weaker than it was before the crisis. The key variable is no longer passenger appetite for travel. It is the duration of the energy shock.

And right now, even the industry's most sophisticated forecasters cannot see the endgame.
