A new warning from U.S. travel and airline groups has turned a political dispute over so-called sanctuary jurisdictions into a practical travel risk for summer 2026. The Department of Homeland Security has been discussing whether to reduce or withdraw U.S. Customs and Border Protection officers from some airport ports of entry, a move industry groups say could disrupt international arrivals, airline schedules, cargo flows and inbound tourism at major U.S. gateways.
No final order has been published, and international flights continue to operate normally. That distinction matters. For travelers, the immediate takeaway is not to cancel a trip because of the proposal. The real significance is that customs staffing has become a fresh uncertainty at exactly the moment when the United States is trying to welcome more international visitors, prepare for World Cup traffic and keep summer air travel moving through already busy hubs.
What happened
Homeland Security Secretary Markwayne Mullin has said the administration is drawing up plans that could stop or reduce the processing of international travelers and cargo at airports in jurisdictions the administration describes as sanctuary cities. The idea would involve moving CBP personnel away from certain airport operations, according to multiple travel-industry reports and wire coverage.
The issue escalated on May 29, when a coalition of travel organizations representing airports, airlines, hotels and other business and consumer stakeholders urged DHS not to take actions that would significantly reduce CBP operations at U.S. airport ports of entry. Airlines for America said the groups warned that disruptions at major international gateway airports would have nationwide consequences for travelers, businesses, supply chains and airport operations.
U.S. Travel Association separately warned that removing CBP officers from Newark Liberty International Airport or other international airports would cause immediate and lasting harm. Business Travel News reported that Newark had been specifically cited in the latest discussion, while also noting that the proposal remained only a possibility as of May 29.
Why it matters for the U.S. travel market
CBP airport processing is not a small back-office function. It is the mechanism that allows international passengers and cargo to be cleared into the United States. If staffing were sharply reduced at a major gateway, airlines could face longer arrival queues, missed connections, schedule changes or, in a more severe scenario, the need to cancel or reroute some international service.
The risk would not be limited to one city. The U.S. international air network is built around large gateways where overseas flights connect into domestic systems. A traveler arriving through Newark Liberty International Airport, New York JFK, Los Angeles International Airport, Chicago O'Hare or San Francisco International Airport may be continuing onward to smaller U.S. cities. Disruption at the first port of entry can ripple across itineraries, aircraft rotations and crew schedules.
That is why the airline and tourism response has been unusually direct. Airlines for America has warned that reducing CBP staffing at major airports would damage airline and tourism operations and disrupt travelers and cargo. U.S. Travel has framed the issue as an economic threat as well as a passenger inconvenience, emphasizing that U.S. citizens returning home and international visitors should not become leverage in immigration-policy disputes.
The timing is especially sensitive
The United States is entering a summer travel season already shaped by high demand, tight airport capacity and close public attention to the country’s ability to handle global visitors. U.S. Travel’s spring forecast projects international inbound spending to rise to $178 billion in 2026, supported in part by major global events including the FIFA World Cup. But the same forecast cautions that inbound recovery remains sensitive to policy conditions, traveler sentiment and geopolitical stability.
That context makes customs-processing uncertainty more consequential than an ordinary Washington policy dispute. The U.S. is still rebuilding some inbound markets after a weak 2025, and major gateways are central to that recovery. International travelers often choose destinations based not only on attractions and airfares, but also on confidence that entry procedures will be predictable.
For travel advisors, tour operators, corporate travel managers and event planners, the concern is operational. Groups arriving from overseas need dependable entry processing, same-day domestic connections, hotel blocks and ground transportation. Even a threat of disruption can force planners to build in more buffer time, review contract terms and prepare alternate routing plans.
What travelers should do now
Because no airport has lost CBP processing under this proposal, travelers should treat the situation as a monitoring issue rather than a reason to abandon plans. Still, anyone booking international travel into the United States over the next several weeks should avoid unnecessarily tight connections after arrival, especially when entering through a major gateway mentioned in coverage of the proposal.
Practical steps include:
- Leave extra time between an international arrival and a domestic connection, particularly for separate-ticket itineraries.
- Book directly with airlines or trusted travel advisors when flexibility and fast rebooking support are important.
- Monitor airline alerts, airport notices and official DHS or CBP updates before departure.
- Keep passports, visas, ESTA approvals and other entry documents organized and accessible to avoid avoidable processing delays.
- For cruises, tours and major events, consider arriving a day earlier when the trip depends on a fixed departure or nonrefundable schedule.
Travelers using Boston Logan, Seattle-Tacoma or other internationally connected airports should apply the same logic: the risk is not limited to one airport until DHS defines the scope of any action, and large U.S. gateways are connected through airline networks.
What to watch next
The key question is whether the proposal remains rhetoric, becomes a formal DHS directive, or is narrowed after industry pushback. Transportation Secretary Sean Duffy has publicly expressed skepticism about restricting air travel based on local politics, according to AP coverage carried by Travel Weekly. That matters because any change affecting major airports would involve not only immigration enforcement priorities, but also aviation operations, airline schedules, cargo logistics and the broader U.S. visitor economy.
For now, the safest reading is conservative: there is no current shutdown of international processing at the affected gateways, but the threat is serious enough that the travel industry is treating it as a material risk. Travelers should keep plans flexible, avoid fragile connections and watch for official updates. For the U.S. travel market, the episode is another reminder that border processing capacity is now one of the most important pieces of the summer travel experience.
