The Jet Fuel Crisis Is Overwhelming Airlines, Governments, and Summer Travel Plans

Fare increases and fuel surcharges have become the most visible response for passengers. Qantas, SAS, Air New Zealand, Cathay Pacific, AirAsia, and Thai Airways are among the many carriers that have announced airfare hikes directly linked to the fuel spike . Cathay Pacific CEO Ronald Lam noted in March that the carrier’s fuel cost had already doubled compared with the previous two-month average, prompting the airline to update its fuel surcharges across affected routes . In the United States, United Airlines CEO Scott Kirby has warned that fare increases are inevitable, with long-haul international routes likely to see the steepest relative impact .

Behind the scenes, airlines are also cutting capacity and rethinking their networks. IATA’s March 2026 data showed global seat capacity growth already slowing sharply, and industry analysts expect further contractions . Airspace closures over conflict zones are forcing costly detours, inflating both fuel consumption and flight times, while some services are being canceled outright .

Fuel hedging—locking in prices months or years ahead—has created a sharp divide between carriers. Those with substantial hedges in place before the conflict are partially protected from the worst of the spot price shock. Others, exposed to the daily spot market, are watching many pre-booked flights turn loss-making on every departure .

Governments and the IEA: Record Reserve Releases and Dire Shortage Warnings

The policy response has been swift and historic in scale. In March 2026, International Energy Agency member nations agreed to the largest emergency oil stock release in the organization’s history—over 400 million barrels, comprising more than 70% crude oil and the rest refined products . The United States alone committed 172 million barrels from its Strategic Petroleum Reserve, with deliveries staggered over 120 days . Further loan tranches from the reserve followed in April, adding tens of millions more barrels to the market .

G7 finance ministers convened emergency calls with the IEA to coordinate the releases, underscoring the severity with which governments view the crisis .

Yet these releases are a temporary bridge, not a permanent fix. The IEA has warned that Europe has replaced only about half of the jet fuel supply lost from the Middle East . On April 16, IEA chief Fatih Birol said Europe had “maybe six weeks or so of jet fuel left” before shortages become a physical reality on the continent . Days earlier, Airports Council International Europe wrote to the European Commission cautioning that systemic shortages of aviation fuel could begin as early as the start of May if tankers do not resume passage through Hormuz .

Analysts and Rating Agencies: Downgrades, Defaults, and Operational Minimums

The longer the Strait of Hormuz remains blocked, the more existential the threat to airline finances.

S&P Global Ratings warned in early March that global airline credit ratings could come under pressure if fuel prices remain “higher for longer” . Fitch Ratings similarly flagged rising disruption risks . Bankruptcy warnings soon followed: Ryanair boss Michael O’Leary predicted that “two or three European airlines could go bankrupt” this winter if the strait stays closed into the summer season .

On the energy supply side, analysts are tracking inventory depletion with growing alarm. JPMorgan analyst Natasha Kaneva warned in May that OECD oil inventories could hit “operational stress levels” by early June and “operational minimum” thresholds by September—the bare minimum needed for pipelines, storage tanks, and export terminals to function—if the strait does not reopen .

What This Means for Summer Travel

For travelers, the consequences are material and likely to worsen. Airfares on many routes have already risen, and additional fuel surcharges are being layered onto bookings. As capacity is cut and flights are canceled or rescheduled, those with summer holiday plans should prepare for fewer available seats, higher last-minute prices, and the possibility of mid-trip disruptions.

IATA’s pre-war profit projection of $41 billion has been overtaken. The industry’s focus has shifted from expansion to survival . Strategic reserve releases can soften the immediate price shock, but they cannot substitute for the 25% of global jet fuel exports that normally flow through the Strait of Hormuz. Unless the route reopens, Europe’s jet fuel inventories will continue shrinking, and the risk of outright shortages at major airports this summer remains elevated.

The situation is fluid and hinges on geopolitics as much as markets. But one outcome is already locked in: summer 2026 will be more expensive, less convenient, and far less certain than anyone planned for.
