New plan for US entry controls may affect several major airports: what does this mean for Hungarian travelers now?

A fresh and important US development for Hungarian travelers is that US homeland security leadership has suggested on several occasions in recent days that customs and entry processing for international passengers and goods could be halted at airports in certain so-called "sanctuary city" cities. According to the current state of the plan, it is not yet an implemented measure, but rather a matter of preparation and political pressure, but it is already a strong enough signal for passengers planning summer and autumn USA trips to take it seriously. Especially because among the mentioned airports are several hubs that European and Hungarian travelers regularly use for direct arrival, further connection, or domestic transfer.

Reuters reported on May 21, 2026, that Homeland Security Secretary Markwayne Mullin told travel and aviation stakeholders in a private conversation that authorities could halt the processing of international passengers at major airports such as Denver, Philadelphia, Chicago, Los Angeles, New York, Newark, Seattle, or San Francisco. The AP later wrote that the US travel industry reacted with serious concern to the suggestion, as such a decision would not only be a political message but could also cause direct operational disruptions in one of the country's most important tourism and business infrastructures. According to another Reuters report on May 26, 2026, Mullin has already spoken publicly about the government working on plans for such a step.

What has changed in recent days?

The weight of the story does not lie in the fact that a closed, effective rule has already come into force, but in the fact that the matter has moved through three levels in a few days. First, it appeared as a background conversation, then it triggered industry protest, and finally, it became a public political message. This rapid escalation is important because the travel market does not only react to actually implemented rules: uncertainty already affects booking decisions, route planning, and airline capacity management.

If international entry processing were to truly cease or significantly decline at a major US airport, the immediate consequence would be the diversion of flights, the reorganization of connections, the complication of baggage handling, and an increase in waiting times related to border crossing. Even the mere possibility could encourage airlines and passengers to plan with greater safety margins, especially during the peak summer season.

Which airports may be affected, and why is this important from a European perspective?

Among the airports mentioned by name by Reuters, several are not just US domestic gateways, but significant international hubs. In the New York area, for example, JFK Airport and Newark Liberty Airport are key players in traffic arriving from Europe. Similarly important is the Philadelphia International Airport, which is particularly interesting for Hungarian readers this season, as it has once again become a more direct and obvious US entry point from Budapest. In the case of Chicago, O'Hare Airport is one of the largest transatlantic transfer gateways, while on the West Coast, Los Angeles, San Francisco, and Seattle also play a prominent role in tourism and business travel.

From a Hungarian perspective, this is significant because a large part of those traveling to the United States do not use a single US airport as a final destination, but fly from there to another state, start a road trip, or create an itinerary involving several cities. In such a situation, the uncertainty of a single entry point can rewrite the logic of the entire trip. For example, it matters whether a passenger books toward Philadelphia, New York, or Chicago if the operational risk is higher on one of the routes later.

Why did the travel industry react so sensitively?

According to the AP report, stakeholders in the US travel sector criticized the idea in particularly strong terms. There is a good reason for this. International passenger traffic is not just about airlines: hotels, conference centers, car rental agencies, attractions, and catering establishments in the affected cities also depend heavily on foreign visitors. If a major airport were to lose or limit its international reception capability, the impact would extend far beyond the terminals.

The issue is also delicate in terms of timing. The peak summer season is now starting in the Northern Hemisphere, when transatlantic demand is traditionally strongest. In tourism, not only the saturation of current flights matters at this time, but also how much passengers dare to book in advance. Such a signal increases uncertainty, and uncertainty usually pushes the market toward more flexible, more expensive, or postponed purchasing decisions.

What does this mean for Hungarian travelers in practice now?

First and most importantly: there is currently no general US ban or new entry rule in effect for these airports. Hungarian travelers therefore have no reason for panic-driven cancellations solely because of this. For those departing in the coming days or weeks, the most important task remains to monitor the official communication of their airline, the departure and arrival airports, and the US authorities.

At the same time, for those booking now, more cautious planning is justified. For summer trips to the USA, it is worth prioritizing modifiable or partially refundable tickets, especially if the route is based on a hub that was mentioned by name in the statements. If someone is planning a US road trip involving several cities, it may be particularly important to leave enough time at the first entry point for potential longer waits or schedule changes.

For those tied to fixed dates due to business trips, conferences, or family visits, a more direct entry logic may be particularly useful now. If there is a realistic choice between two or three US gateways, the decision should consider not only price and travel time, but also how vulnerable the given route is amidst current political and operational uncertainties.

What should be considered before booking?

• Check if the first US arrival point is among the currently mentioned affected airports.
• If making a new booking, consider the advantages of a flexible fare or a more easily modifiable connection.
• Leave a larger time buffer between entry and domestic onward travel.
• Check not only the airline but also the latest announcements from the specific airport and US authorities.
• If planning a group or family trip, it may be particularly important that the entire itinerary does not rely on a single tight connection.

Why could this be particularly important now, when Hungarian-US relations are strengthening again?

In recent weeks, it has had particular news value for Hungarian travelers that more attention is being paid to flights and transfer options to the United States. In this environment, any development that could affect the operation of an important US entry point immediately becomes a practical question. Not only for classic city visitors, but also for those departing for family visits, study trips, work, or conferences.

Philadelphia is a particularly interesting example in this regard, because the city can be both a final destination and a transfer hub. And if attention shifts toward East Coast gateways, it makes the role of New York and Newark even more sensitive. For Midwest and West Coast onward travel, the stability of Chicago, Los Angeles, San Francisco, and Seattle matters a lot.

What is the most likely scenario?

Based on current information, the most likely short-term scenario is not an immediate national travel shock, but prolonged uncertainty. That is, it is quite possible that more statements, political debates, and industry counter-reactions will follow in the coming days and weeks, while the actual implementation details remain not fully clear. In such situations, the best strategy for the passenger is flexibility: not to overdramatize the situation, but not to book as if no risk existed.

It is also an important point that the US air transport system is highly networked. The uncertainty of a major entry point can quickly spread to other cities, either in the form of higher fares, diverted traffic, or less favorable connection times. As a Hungarian traveler, therefore, it is not enough to just see if your own final destination is affected: it is also worth considering which route you take to get there.

Summary

The current US development became one of the most important tourism news of the week because it directly affects the basic condition of entry, namely the processing of international arrivals, and moreover at several major airports that European and Hungarian passengers regularly use. The plan has not yet been implemented, therefore currently not panic, but conscious route selection is the correct reaction. Those organizing USA travel now should pay more attention than usual to the selection of the entry point, connection buffers, and flexible booking conditions.

If the matter eventually becomes a real measure, it will have a rapid effect on US tourism and transatlantic travel. And if it does not become an implemented rule, it is already instructive how quickly political uncertainty can become a travel planning issue. Therefore, for Hungarian travelers, the best approach now is to monitor, compare, and plan their US gateway city a degree more cautiously than usual.
