KLM Cuts 160 European Flights as the Fuel Crisis Gripping Aviation Deepens

Royal Dutch Airlines has moved swiftly to confront one of the most severe cost pressures in recent European aviation history, confirming on Thursday the cancellation of 160 flights to and from Amsterdam Schiphol Airport within the coming month. The decision, announced on the same day the head of the International Energy Agency warned that Europe has only weeks of jet fuel supplies remaining, lays bare the mounting financial strain that the ongoing Middle East conflict is inflicting on carriers across the continent.

The Decision and What Is Being Cut

Dutch airline KLM on Thursday said it would cancel 160 flights in Europe in the coming month due to rising fuel costs. KLM says increased fuel costs mean a limited number of flights within Europe are no longer financially viable to operate. 

In total, KLM will cancel 160 flights, divided evenly between departures and arrivals at Schiphol Airport. These cancellations are round-trip pairings, which represent about one percent of KLM's European schedule. 

The scrapped flights are all to cities such as London and Düsseldorf, where KLM flies several times a day, so there are plenty of alternatives, the airline said. Passengers booked on cancelled services will, according to KLM, be rebooked onto the next available departure on the same route.

Despite the scale of the cuts, KLM was firm in distinguishing financial necessity and operational crisis. There is currently no question of a kerosene shortage, KLM said. KLM also said it expects a busy May holiday period and that it is "making sure passengers can travel to their holiday destinations as planned." 

The Root Cause: A Middle East Conflict That Has Reshaped Global Energy

The cancellations cannot be understood in isolation from the wider geopolitical shock that has gripped global energy markets since late February 2026. European airlines from budget carrier Wizz Air to network giants SAS, Lufthansa, and KLM are scrambling to contain a sudden surge in jet fuel prices as war in Iran and a wider Gulf conflict squeeze global oil supplies, disrupt key air corridors and threaten to stall the fragile recovery in international travel in 2026. 

Benchmark European jet fuel prices reached an all-time high of $1,838 per tonne by April 11, 2026, compared to $831 prior to the conflict. For an airline of KLM's scale, operating an average of close to 800 flights per day, even a marginal reduction in per-flight viability rapidly translates into hundreds of uneconomic departures each month.

The closure or restriction of multiple Gulf and Levant airspaces is forcing aircraft to detour thousands of extra kilometres around conflict zones, adding fuel burn and crew time on already expensive intercontinental sectors. The net effect is a compounding of costs: higher fuel prices at the pump, combined with more fuel consumed per flight due to longer routing.

IEA Issues a Stark Warning on the Same Day

KLM's announcement landed on an already deeply unsettling day for European aviation. Europe has "maybe 6 weeks or so (of) jet fuel left," the head of the International Energy Agency said Thursday in a wide-ranging Associated Press interview, warning of possible flight cancellations "soon" if oil supplies remain blocked by the Iran war.

IEA Executive Director Fatih Birol painted a sobering picture of the global repercussions of what he called "the largest energy crisis we have ever faced," stemming from the pinch-off of oil, gas and other vital supplies through the Strait of Hormuz. 

Birol said: “In the past, there was a group called 'Dire Straits.' It's a dire strait now, and it is going to have major implications for the global economy. The longer it goes, the worse it will be for the economic growth and inflation around the world.”

Birol also cautioned directly that if the Strait of Hormuz remains closed, "I can tell you soon we will hear the news that some of the flights from city A to city B might be canceled as a result of lack of jet fuel." 

European airport association ACI Europe warned that a shortage of aviation fuel could emerge by the end of April. Marnix Fruitema, the chair of airline trade group BARIN, predicted in early April that airlines would be forced to begin cancelling flights by mid-May to save fuel, telling ANP he expected this to affect intercontinental flights even more than European flights, particularly on routes to and from Southeast Asia, which relies on kerosene from the Gulf region. 

KLM's Wider Network Under Pressure

The European route cuts are only one dimension of KLM's current operational challenge. KLM Royal Dutch Airlines is currently operating a reduced Middle East network due to the ongoing regional conflict and EASA airspace restrictions. The airline's summer 2026 schedule runs from 29 March to 25 October 2026, covering 164 destinations, 96 in Europe and 68 intercontinental cities, with an overall 5% increase in seat capacity compared to summer 2025. 

Flights to and from Dammam and Riyadh are suspended up to and including Sunday 17 May 2026. Flights to and from Dubai are suspended up to and including Sunday 14 June 2026. 

Even routes that are technically operating — such as Amsterdam to Bangkok, Singapore, and Tokyo — are subject to rerouting around Middle Eastern airspace, adding 2–4 hours to typical journey times on some routes. 

Air France-KLM is preparing for possible fuel shortages in parts of the world, particularly in Southeast Asia. Unlike Europe, where fuel supplies are relatively stable, many Asian destinations rely heavily on imports from the Gulf region. As a result, aircraft may be able to fly out, but may not be able to refuel sufficiently for the return flight. 

A Wider European Reckoning

KLM is far from alone in its response. Earlier on Thursday, German carrier Lufthansa outlined plans to remove the flying capacity of its regional carrier Lufthansa CityLine as part of measures to counter fuel cost volatility. Lufthansa announced a cost-cutting plan on Thursday, outlining measures to reduce capacity and retire older aircraft. 

Air France-KLM CEO Ben Smith said the consortium's airlines were making plans to contend with a kerosene shortage. The group, which also owns Transavia and cargo carrier Martinair and holds a large stake in SAS, faces the same structural exposure to Gulf-priced jet fuel as its peer carriers.

KLM said that "At this time, there is no acute fuel shortage, and we are operating our flights as scheduled," adding that it is "analysing various scenarios that could potentially impact our operations," including the possibility of a fuel shortage resulting from the blockade in the Strait of Hormuz.

Meanwhile, Dutch Infrastructure Minister Vincent Karremans told Parliament that the Netherlands and Europe have at least "five months' worth of kerosene reserves," during a debate on April 7. That assessment, however, is now being directly challenged by the IEA's more acute estimate of six weeks, highlighting the speed at which the crisis is evolving.

KLM Suspended and Affected Route Operations 

All times are local. London and Düsseldorf frequencies are reduced as part of the 80 European return-flight (160 one-way) cancellation programme, effective from late April into May 2026. Passengers on affected services will be rebooked on alternative KLM departures on the same day.

Timing Could Not Be Worse

Complicating matters is the upcoming school holiday, which begins when classes let out on April 24, with students due back in their seats on the morning of May 4. The national holiday of Koningsdag, or King's Day, also takes place on April 27, with Remembrance Day on May 4 and Liberation Day on May 5. 

For KLM, trimming 1% of its European schedule during one of the busiest leisure travel periods of the Dutch calendar is a carefully calibrated move, disruptive enough to generate significant cost savings, but surgical enough to preserve the overwhelming majority of holiday travel demand.

The airline's insistence that all affected passengers can be accommodated on alternative departures on high-frequency routes like London and Düsseldorf reflects the logic of cutting where the network can absorb the impact. The coming weeks will test whether that calculation holds, and whether the fuel crisis deepens to the point where far larger cuts become unavoidable across European aviation.
