More Expensive, Longer, Rarer? What the Slowdown in European Air Connectivity Means for Hungarian Travelers Before Summer

Before the 2026 summer season, several fresh industry signals indicate that the power of demand and a cautious restraint in supply are present simultaneously in European air transport. On May 21, IATA reported that the growth of European air connectivity practically flattened in 2025, while according to EUROCONTROL, airlines have already reduced the planned number of flights in the May-June schedules compared to April levels. In the background, the impact of the Middle East crisis continues: longer routes, more fragile fuel supply, more selective capacity allocation, and a greater focus on higher-yield markets.

This does not mean that the summer travel season is collapsing or that mass cancellations are coming. On the contrary, several market players specifically emphasize that the summer program is achievable. The important message is rather that in the summer of 2026, passengers will need to plan slightly more consciously. From the perspective of Hungarian travelers, this is significant because, in addition to departure points around Budapest, many also fly from Vienna, and in a tighter European scheduling environment, even a small route or capacity correction is enough to make tickets more expensive, reduce convenient departure times, or make transfers more difficult.

What do the latest data show?

According to IATA's May 21 announcement, the net growth of the European route network in 2025 was only 1 percent. Based on the organization's data, 1,127 routes ceased to exist, 1,281 started or returned, meaning the net expansion was only 154 routes. On paper, this is still growth, but in practice, it indicates that continuous network densification is no longer a given in Europe. Markets where operating costs are high, yields are lower, or demand is more uncertain are more likely to fade into the background.

This aligns with the weekly overview published by EUROCONTROL in mid-May. According to the organization, airlines planned an average of 2 percent fewer flights in the May-June schedules than they had indicated for the same period in April. The explanation is particularly important: carriers are prioritizing routes that generate higher profits. This behavior is completely rational, but from the passenger's perspective, it means that flights connected to less strong, seasonally fluctuating, or alternative airports may be more sensitive to fine-tuning.

The same EUROCONTROL report also showed that traffic between Europe and the Middle East is still severely disrupted: the number of flights lagged 38 percent behind the level of one year earlier. Additionally, due to detours avoiding conflict zones, the network overall operates with longer flights, additional fuel consumption, and schedules that are harder to optimize. Although the average kerosene price decreased by 12 percent in two weeks by May 8, according to EUROCONTROL, it was still approximately 1.75 times the pre-crisis level. This alone is enough for airlines to handle capacity more cautiously.

Why does the Middle East situation matter so much if someone is traveling within Europe?

Many passengers rightly think that the Middle East crisis mainly affects those flying to or from the region. The reality is more complex. International air transport operates on network logic: if an airspace closure, a major detour, fuel supply uncertainty, or aircraft rotation disruption appears in one region, its effect can easily ripple through to other markets. Not necessarily in the way that a Budapest or Vienna holiday flight suddenly disappears, but rather that an airline prefers to keep capacity on its more stably profitable routes and thins it elsewhere.

The European Commission already issued separate guidance on May 8 for EU transport and tourism players on handling fuel and route problems resulting from the Middle East crisis. This alone indicates that this is not merely temporary market noise. The Commission made it clear that airlines cannot impose subsequent fuel surcharges on pre-purchased tickets, and passengers continue to be entitled to EU rights in case of flight cancellations, namely rebooking, refund, assistance, and in some cases, compensation. This is an important safety net, but it does not replace proactive planning.

EASA issued a separate safety notice on the same day regarding the European use of Jet A fuel, as the supply of traditionally used Jet A-1 came under pressure. This may seem like a technical detail, but in reality, it well demonstrates that the crisis is no longer just geopolitical news, but an operational issue. If the industry's regulatory and safety bodies are dealing with alternative fuel management at this level, then the summer operations of airlines will inevitably be characterized by greater caution.

Is there reason to panic? Briefly: no, but blind optimism is also unjustified

The picture is not unilaterally negative. Jet2 announced on May 20 that based on discussions with suppliers, production has increased and further imports are arriving from regions not affected by the conflict, so the company remains confident that it can fly its summer program as planned. This is an important signal because it shows that there are not only disaster scenarios in the market, but also adaptation mechanisms. On the demand side, there is also no collapse. According to ACI EUROPE, passenger traffic at European airports grew by 3.8 percent year-on-year in March, despite the conflict.

In other words, the main scenario for the summer season is currently not mass flight cancellations, but a tighter, less generous scheduling environment. Those who are flexible will likely still find a suitable route. However, those who can only depart within a single narrow time window, insist on a specific transfer combination, or book very late, may more easily face higher prices and fewer options.

What does this mean specifically for Hungarian travelers?

First, it is worth paying more attention to schedule changes than usual. If someone departs from Budapest Airport, it is advisable to check the departure time and any possible modifications not only at the moment of booking but also in the weeks preceding the trip. The same applies to those who use Vienna Airport as an alternative, because in a dense summer schedule, a small flight reduction or aircraft change can quickly rewrite the travel day.

Second: the role of comfort buffers is increasing. For those whose plane departs at dawn or who have a connecting route, it is even less advisable this year to calculate everything to the minute. If the chosen route departs from Vienna, it may be worth arriving the previous evening and choosing one of the hotels near Vienna Airport. For departures from Budapest, a pre-booked airport transfer in Budapest may be a practical solution for many passengers, especially if the airline or airport requests an earlier arrival than average.

Third: it is worth distinguishing real risk from excessive noise. Based on fresh industry data, it does not appear that European summer air transport is paralyzed, but rather that airlines are managing capacity more disciplinedly. This may be bad news for those who want to choose from cheap, frequently modifiable options at the last minute, but not necessarily bad for those who book in time, monitor changes, and accept that the summer of 2026 will be less predictable than in a calmer year.

What should be considered before booking?

The most important question now is not whether we should fly, but how to book smartly. It is worth checking whether there are multiple departures per day on a given route, or only a few per week. The latter are more fragile because if the airline adjusts the schedule, there is little reserve. It is also essential to see whether it is a direct or connecting route. A direct flight may be more expensive, but in an uncertain market environment, it often represents less risk than a route built with a tight connection.

It is also not insignificant what conditions we book under. Since the European Commission's position is that fuel surcharges cannot simply be added to the fare of already purchased tickets, the biggest risk now is not this, but schedule modifications and possible flight consolidations. Therefore, flexible rebooking, easily accessible customer service, and a clear notification system may be worth more than the absolute cheapest fare.

Summary

Based on the European picture seen in the last week of May, the summer travel market is not weak, but tense. Demand persists, but airlines and airports are preparing for the peak season in a more complex, cost-sensitive, and geopolitically fragile environment. Fresh data from IATA shows that Europe's route network is barely expanding, according to EUROCONTROL, companies are already shifting capacity toward more profitable routes, and the European Commission and EASA have reacted to fuel risks at the regulatory and safety levels.

For Hungarian travelers, this means that it is still possible to plan a good trip for the summer of 2026, but it is less advisable to book out of routine. Those who monitor schedules, leave a buffer around the departure day, consciously choose the departure airport, and think ahead about ground logistics, will likely avoid most of the unpleasant surprises of the season.
