The EU Prepares for Jet Fuel Risks: What Should Hungarian Travelers Watch for Before the Summer Season?

On May 18, 2026, the European Commission spoke not only about general crisis monitoring but also held a separate consultation on the European situation regarding jet fuel supply. The essence of the fresh message is reassuring but not indifferent: there is currently no fuel shortage in the EU; however, regional disruptions could develop in the coming weeks if obstacles to oil shipments passing through the Strait of Hormuz persist. For Hungarian travelers, this does not mean immediate summer chaos, but rather that schedules, prices, and the risks of certain longer routes may be more sensitive than usual.

The current development is important because the Commission, by bringing energy, transport, and market players to the table, is specifically preparing for the kerosene situation. This indicates that European decision-makers are not treating the matter as a theoretical problem, but as a factor that could directly affect the summer travel season. The issue is particularly relevant for Hungarian passengers who not only fly within Europe but travel to Asia, Africa, or Australia via Middle Eastern transfers, or those who choose long-haul flights whose routes may be indirectly affected by current airspace and supply disruptions.

What Exactly Happened Now?

The Directorate-General for Energy of the European Commission announced on May 18 that at the Oil Coordination Group meeting, representatives of the Commission, EU member states, the International Energy Agency, NATO, and the industry examined European security of supply. According to the current official position, there is no fuel shortage at present, but if the situation around the Strait of Hormuz is not resolved, regional supply constraints may appear in the coming weeks, and within this, jet fuel is the most sensitive point.

This is an important nuance. The Commission did not say that Europe is running out of kerosene, but that the situation could become more tense in certain regions, at certain airports, or in certain supply chains. From a passenger's perspective, this is significant because even a minor supply uncertainty in air transport can cause delays, more cautious schedule planning, route modifications, or higher costs.

The Commission also indicated that EU emergency reserves could be accessed if necessary, but only in a coordinated manner and likely alongside austerity measures. This in itself suggests that Brussels does not automatically view the beginning of summer as stable, but as a period requiring continuous monitoring.

Why Has Jet Fuel Become the Main Issue Now?

The current risk does not stem solely from the world market price of oil. According to European authorities, the problem is rather that the Middle Eastern conflict affects not only prices but also physical shipping routes and the availability of refined products. The Strait of Hormuz is a key point for global energy shipments, so disruptions there can bring not just price increases, but logistical uncertainty.

For European airports and airlines, this is sensitive because the system is already strained during the summer peak season. During this time, capacity utilization is higher, there is less buffer in the schedule, and there is less room for a supply disruption to be absorbed unnoticed. If this is combined with detour routes, longer flight times, or the reorganization of fuel uptake, the problem can quickly ripple through into the daily passenger experience.

EUROCONTROL had previously indicated numerically how much the Middle Eastern crisis is distorting the European network. According to an analysis from the end of March, approximately 1,150 flights per day were affected by diversions after the start of the conflict; detour flights resulted in about 206 thousand extra kilometers per day, 602 tons of additional fuel consumption, and 1.9 thousand tons of extra carbon dioxide emissions. These are not today's figures, but they clearly show that the system has been operating with higher reserve consumption for months than in more peaceful periods.

What Did EASA Do, and Why Does This Matter to Passengers?

The European Union Aviation Safety Agency, EASA, issued a safety information notice on May 8 regarding the European use of Jet A type jet fuel. In Europe, Jet A-1 is traditionally widespread, while Jet A is also widely used in North America. The difference between the two fuels may seem like a technical detail at first glance, but according to the authority, switching or parallel use is only safe with proper procedures.

EASA warned the industry that due to the higher maximum freezing point of Jet A, airlines, airports, and ground handling organizations must review their own procedures. As a Hungarian traveler, the takeaway is not that flying has become less safe, but exactly the opposite: European authorities issued the technical guidance even before a broader application became necessary. This is a sign of prevention.

However, such technical and operational transitions can have indirect effects. If extra checks, different ground processes, or more cautious fuel planning are required at certain airports or by certain airlines, it can slow down operations, even if the passenger only perceives this as their flight departing later, their route changing, or their connection time becoming less favorable.

What Does All This Mean for Hungarian Travelers in Summer 2026?

The most important thing is that summer travel does not need to be canceled or rescheduled in panic. Based on the Commission's current position, there is no general European fuel shortage. The risk is rather that the market has become more sensitive, so price increases, schedule fine-tuning, or longer connection uncertainties may appear more quickly on certain routes.

The most exposed group may be those traveling through Middle Eastern hubs. If someone transfers at Hamad International Airport in Doha or Dubai Airport to a destination in Asia, the Indian Ocean, or Australia, they should pay close attention to airline notifications, as airspace conditions, longer detours, and fuel planning together can cause greater variability on these routes.

The second group includes those flying via European transfer hubs. A route passing through Frankfurt, Vienna, Paris, or Berlin may seem distant from the Middle Eastern crisis at first glance, but due to the interconnectedness of the European network, disruptions can ripple through here as well. If longer flight times, aircraft swaps, or turnaround time problems occur in other parts of the network, it can later degrade the punctuality of intra-continental flights. Therefore, passengers at Frankfurt Airport or Budapest Airport should also plan more cautiously with tight connections.

The third group consists of purely European leisure travelers. For them, the current news may be more a matter of price than a direct operational problem. The European Commission specifically indicated that high fuel prices alone are a normal business risk for airlines, meaning that price increases do not automatically exempt companies from passenger rights obligations. In practice, this means that summer ticket prices may rise, but not every disruption can be treated as an extraordinary circumstance simply by citing the increase in fuel costs.

What Rights Do Passengers Retain?

This is one of the most important questions. According to the Commission's crisis management guidelines, passengers remain entitled to refunds, re-routing, or return flights, as well as assistance at the airport if their flight is canceled. The document, however, distinguishes between local fuel shortages and high fuel prices. According to the Commission's position, a specific, local fuel shortage may be an extraordinary circumstance, but simply higher fuel costs are not.

This distinction is important because in the minds of many passengers, every crisis situation seems the same. Yet, it matters whether a flight is canceled because there is actually not enough fuel available at a given airport, or because the airline's costs are permanently higher. In the first case, the assessment of the obligation to pay compensation may differ, whereas in the second case, more expensive operations alone do not exempt the company.

On a practical level, this means that Hungarian travelers should keep all communications, monitor their flight status, and if a cancellation occurs, immediately clarify exactly what solution the airline offers: a refund, an alternative route, or a later departure. This is especially important if the trip consists of multiple elements, such as hotels, further connections, or pre-paid programs.

How Should One Book and Prepare Now?

The best strategy now is not rushing, but conscious booking. Those planning a long-haul trip may find it beneficial to keep the route within a single booking, as it is usually easier to enforce rights in a re-booking situation than with separately purchased segments. For very short connections of 60-75 minutes, the risk is currently slightly higher than in calmer periods, so for many passengers, a somewhat longer connection may be a more peaceful decision.

It is also a sensible step for the passenger to re-check their flight a few days before departure, not only in the booking system but also on the information surface of the given airport. For example, someone departing from Budapest may find it useful to monitor information related to Budapest Airport, especially if the onward journey depends on sensitive connections. If someone travels with a Middle Eastern transfer, a preliminary review of accommodation options near the destination or transit airport is not superfluous; in such cases, hotels around Dubai Airport or hotels around Doha Airport can serve as a useful backup plan.

What Is the Most Likely Scenario?

Based on current official information, the most likely summer scenario is not a mass shutdown, but a European system operating with increased nervousness but remaining fundamentally operational. That is, more warnings, more caution, occasionally more expensive tickets, and more schedule adaptations on certain routes can be expected, while the vast majority of travels will still take place.

This is particularly believable because EU institutions reacted on several levels simultaneously: coordination is taking place on the energy side, legal interpretation guidance was prepared on the transport side, and on the safety side, EASA issued the necessary technical warning in advance. This is a sign of preparation, not paralysis. For Hungarian travelers, therefore, the best approach now is not to over-dramatize the situation, but not to treat it as if it were merely distant geopolitical background noise.

Summer 2026 will, by all indications, take place amid strong demand, and in such an environment, even minor external disruptions reach the passenger more quickly. The most important message of the fresh EU signal is therefore that those who fly should now plan more flexibly, monitor airline notifications, and know what rights they are entitled to in case of problems. It is not certain that every passenger will notice anything. But it is certain that this does not promise to be a summer where it is worth blindly assuming that every point of the supply chain remains stable on its own.
