Why your next flight just got cancelled

TL;DR

• Global airlines have cancelled or consolidated 20,000+ flights since 26 March. The cause is jet fuel, not software, strikes, or weather.
• Singapore jet kerosene sits at US$128 a barrel, up 46% from 10 March. The last sustained price above US$120 was the Ukraine-invasion spike. It is higher now.
• Long-haul thin-margin routes are being cut first. Cargo is flying. Premium empty seats are not.
• Fares are up 18–24% on international economy since February and won't fall until the Singapore jet crack narrows below US$25. No path to that without Iranian exports returning.
• The base case: jet fuel at ~US$115 in May, ~US$98 by July. Painful. Bearable. A long way from normal.

The short version

Global airlines have cancelled or consolidated more than 20,000 flights since 26 March, according to carrier advisories compiled by ABC World News Tonight on 22 April. The cause is not weather, not strikes, not software — it is jet fuel. There is not enough of it, it costs too much, and the routes that still make commercial sense have shrunk.

Jet kerosene on the Singapore benchmark is trading at US$128 per barrel, up 46% from its 10 March close of US$87. The last time jet fuel sustained prices above US$120 for more than a week was mid-2022, at the peak of the Ukraine-invasion spike. It is higher now.

Why jet fuel specifically

Crude oil is a commodity. Jet fuel is a product — specifically, a middle-distillate kerosene with tight purity specs, produced mostly by refineries in the Gulf, Singapore, and the US Gulf Coast. When Iran's 1.4 mbd of crude exports vanished in late March, the feedstock for the Gulf refineries feeding Asian aviation vanished with it. Singapore's refinery utilisation has fallen from 94% to 81%. The jet-fuel premium over crude — the "crack spread" — has widened to US$37 per barrel, roughly triple the five-year average.

Airlines buy jet fuel on short-term contracts layered with hedges. Most carriers hedged 50–70% of their 2026 fuel needs at prices struck before the war. The unhedged balance is what is breaking the schedule. At US$128 jet, a Sydney–London route that was marginally profitable at US$85 jet is losing US$18,000 per flight.

Who's cancelling what

The pattern across April has three phases:

1. Route suspension — long-haul, thin-margin routes cut first. Lufthansa suspended Frankfurt–Manila and Frankfurt–Cape Town. KLM cut Amsterdam–Santiago. Virgin Atlantic dropped Manchester–New York. Australian carriers have held the line on mainline international routes but cut frequencies: Qantas moved Sydney–Johannesburg from daily to five-weekly; Virgin Australia consolidated Brisbane–Tokyo with partner ANA.
2. Cargo-first re-routing — freighters are flying, passengers aren't. Jet fuel is so expensive that airlines would rather fly paying cargo than empty premium seats. Cargo rates on trans-Pacific routes are up 31% since 26 March.
3. Regional consolidation — short-haul network carriers are running aircraft fuller by cancelling adjacent flights. Ryanair cancelled 3,400 flights between 1 and 22 April, rebooking passengers onto later departures. Their load factor is now 98%.

The 20,000 figure is not evenly distributed. Europe and the Middle East account for 11,000 of the cuts. The US has shed 3,800. Asia-Pacific 4,200. Latin America and Africa 1,000 combined.

Hype deconstruction — is this as bad as the headlines?

The 20,000-flight figure is real, sourced from carrier advisories, and a week from being out of date (it will be larger). But two things in the coverage are noise.

First, the framing as a "jet fuel shortage". There is no shortage. There is a price. Airlines can buy all the jet kerosene they want at US$128 a barrel. They are cancelling flights because the flights are unprofitable, not because the fuel is unavailable. The distinction matters when you hear phrases like "rationing" or "supply chain breakdown" — neither applies.

Second, the implied collapse narrative. Commercial aviation has absorbed jet-fuel spikes before. The Ukraine-invasion spike in 2022 produced a six-week dislocation. The recovery was real. The 2026 spike is deeper but the industry is more hedged, more consolidated, and has pricing power it did not have in 2022. A collapse case exists only on a ceasefire break, and even then it runs through carrier solvency at specific names (Spirit, PIA, several African carriers) rather than systemic failure.

Cross-layer implications

• Goods inflation: pharmaceuticals, fresh seafood, high-value electronics move primarily by air freight. Expect SKU-level stock-outs through May and June. Not a crisis. A texture.
• Tourism-economy softening: Australian inbound bookings for June–July are running 11% behind 2025, the steepest since early COVID. Regional hospitality markets will feel a softer winter.
• Regulatory pressure: EU and UK passenger-rights regimes are about to face their largest ever compensation event. Multiple billions in AOG-compensation exposure is possible if cancellation waves continue.
• Carrier consolidation: if fuel stays above US$110 into Q3, expect one or two secondary-carrier insolvencies that reshape regional route maps for a decade.

What this means for you

If you have a flight booked in the next 8 weeks — check your carrier's advisory page this week, not the day before. Airlines are consolidating flights 4–6 weeks out, not last-minute. Rebooking options shrink fast once other travellers see the cancellation. If your flight is on a thin route (not a trunk city-pair), assume a 30–40% chance it gets consolidated or cancelled before departure. Book with a carrier that has a same-alliance partner on the route — your rebooking options triple.

If you are paying full fare next quarter — economy fares on international long-haul are up 18–24% since February. Business-class fares are up 9–12%. This is not airline gouging — it is jet fuel passing through. Fares will not fall meaningfully until the Singapore jet crack narrows back below US$25, which requires either Iranian exports returning or a sustained drop in Asian demand. Neither is imminent.

If your business runs on air freight — renegotiate contracts now. Carriers are absorbing roughly one-third of the fuel rise into their own margins and passing two-thirds to customers. The carriers will lose the ability to absorb anything if this runs past June. Lock rates while you can.

If your job depends on the tourism economy — the booking data for Australian inbound tourism in June and July is now running 11% behind 2025, the steepest softening since early COVID. If you work in hospitality in regional tourism markets, expect a softer winter. Budget accordingly.

If none of the above applies — you are about to hear "supply chain issues" attached to products you would not have associated with aviation: pharmaceuticals, fresh seafood, high-value electronics. All of those move primarily by air freight. Expect stock-outs on specific SKUs through May and June. Not a crisis. A texture.

When this resolves

Two paths, both outside your control:

• Ceasefire holds, Iran exports resume — jet fuel eases back toward US$95 over 6–10 weeks as Gulf refinery feedstock normalises. Cancelled routes come back in Q3.
• Ceasefire breaks — jet fuel tests US$150. A further 15,000–25,000 flights drop out over the following six weeks. Some secondary airlines (Spirit, Pakistan International, several African carriers) face solvency questions by August.

The base case, weighted by current futures curves, is somewhere between: jet fuel averages US$115 in May, US$105 in June, US$98 in July. That is painful but bearable for the industry. It is also a long way from normal.

Uncertainty ledger

• Whether Singapore and US Gulf refineries will ramp output to fill the jet crack, or hold utilisation low to protect margins.
• Whether airline cancellation waves will trigger consumer-protection regulatory action in the EU and UK — material for AOG-compensation costs, potentially billions.
• Whether Qantas and Virgin will hold their current route maps through Q3 or follow European peers into deeper consolidation if fuel stays above US$110 through June.

Bottom Line

The 20,000 cancelled flights are the first direct, personal cost of the Iran war for hundreds of millions of households who do not follow oil markets and will not watch a single briefing from Oman. The next flight that gets consolidated, the next fare that comes back 22% higher, the next parcel that arrives late — all of them are the jet-fuel story wearing a different hat. Fares normalise only when Iranian crude returns and Gulf refineries restock. Neither happens before the 6 May ceasefire expiry. Budget accordingly; don't hope for faster.
