Quick summary
The Department of Homeland Security has reiterated it could suspend Customs and Border Protection processing at airports in so-called sanctuary jurisdictions, according to sources briefed on the discussions. JFK, Newark Liberty, Washington Dulles, and Portland International are among the airports reportedly under consideration — gateways that together handle tens of millions of international arrivals annually. No formal order has been issued, but DHS Secretary Markwayne Mullin has made the threat explicitly, including in a meeting with airline and travel industry executives.
Without CBP officers on the ground, international flights cannot legally process arriving passengers — meaning the threat is not rhetorical inconvenience but a potential operational shutdown. Any formal directive would force airlines to reroute or cancel international services within days.
A high-level policy threat from the Trump administration is putting international travelers on notice. DHS Secretary Markwayne Mullin has told airline executives directly that the federal government may reduce or suspend Customs and Border Protection staffing at airports in cities that limit cooperation with Immigration and Customs Enforcement — a category the administration labels “sanctuary jurisdictions.” The airports named in those discussions include JFK, Newark Liberty (EWR), Washington Dulles (IAD), and Portland International (PDX).
This is not a scheduling dispute or a labor negotiation. International flights cannot operate without CBP officers to process arriving passengers and cargo. If staffing is pulled or significantly reduced at any of these airports, airlines face an immediate choice: reroute through unaffected hubs, or cancel international services entirely.
The threat follows Mullin’s public remarks questioning whether sanctuary cities “deserve” to process international customs arrivals — and it has now been reiterated in private meetings with the industry. No formal directive has been issued as of publication. But the gap between political rhetoric and an operational order is narrowing, and travelers with bookings at these airports in the coming weeks are exposed.
Reporting confirms that any action would likely be timed after the 2026 FIFA World Cup concludes in July — which tells you something. Even DHS appears to understand that disrupting international arrivals during a global sporting event would be catastrophic. The same logic applies every other week of the year.
What a CBP staffing cut actually does to an airport
The mechanism here is straightforward and brutal. Under 8 U.S.C. § 1225, all arriving international passengers must be inspected by CBP officers at a designated port of entry. There is no workaround, no self-processing option, no airline substitute. Remove the officers, and international arrivals stop — legally, not just logistically.
United Airlines operates Newark as its primary New York-area hub, with transatlantic and some transpacific services feeding an extensive domestic network. Delta Air Lines, American Airlines, JetBlue, and dozens of foreign carriers use JFK as a major international gateway. Alaska Airlines anchors Portland. Washington Dulles is a key Star Alliance hub for United’s European and Middle East services. These are not interchangeable facilities — each has specific international terminal infrastructure, gate allocations, and slot rights that cannot simply be transferred to Atlanta or Dallas overnight.
The ripple effect runs in both directions. A Korean family connecting at JFK to Orlando, a German executive clearing Newark before a domestic connection to Cincinnati, an Australian traveler transiting Dulles on the way home — all of them become stranded the moment CBP processing stops. Cargo shipments moving on just-in-time logistics through these gateways face the same wall.
Reuters confirmed the threat based on two sources briefed on the discussions, and official statements from DHS have not walked it back. The Reuters report notes Mullin reiterated the possibility after earlier public remarks on Fox News — this is a position being repeated, not floated once and forgotten. This pattern of federal pressure on travelers is part of a broader shift: ATC’s earlier coverage of TSA sharing 31,000 traveler records with ICE shows how aviation infrastructure is increasingly being used as an immigration enforcement tool.
| Airport | Primary hub carriers | Key international links | Min. intl-to-domestic connection | Nearest alternative |
|---|---|---|---|---|
| JFK (New York) | Delta, JetBlue, American + foreign carriers | Tokyo, Seoul, Hong Kong, London, Paris | 2–3 hours (immigration + terminal transfer) | EWR (United hub, same metro) |
| EWR (Newark) | United Airlines | Transatlantic, select transpacific, domestic network | 1.5–2 hours airside | JFK (15 miles, different carrier base) |
| IAD (Washington Dulles) | United Airlines (Star Alliance hub) | Europe, Middle East, some Asia services | 1.5–2 hours (Aerotrain assists) | BWI (Southwest-focused), DCA (mainly domestic) |
| PDX (Portland) | Alaska Airlines focus city | Canada, limited long-haul seasonal routes | 1–1.5 hours (simpler layout) | SEA (Seattle-Tacoma, major Alaska/Delta hub) |

Why there is no easy reroute — and what the law actually says
The administration’s implicit assumption — that airlines can simply redirect international traffic to “cooperative” airports — misunderstands how the system is built. Hub infrastructure is fixed. International-capable terminals, CBP inspection facilities, gate allocations, and slot rights at airports like JFK took decades and billions of dollars to develop. You cannot absorb thousands of daily international passengers at Atlanta or Dallas-Fort Worth on short notice without cascading delays at those airports too.
On the legal side, DHS oversees CBP operations under 8 U.S.C. § 1225 and faces no regulatory obligation to maintain specific staffing levels at any airport. The FAA retains safety oversight and airport operating certificates under 14 CFR Part 139, but that authority covers aviation safety — not immigration processing. Flights can only operate international arrivals where CBP processing is available. The FAA cannot compel DHS to staff an inspection facility.
Passenger rights protections offer limited shelter here. For flights departing the EU or UK, EU261/2004 and UK261 compensation generally does not apply to cancellations caused by government decisions — courts treat these as extraordinary circumstances. Airlines must still offer rerouting or refunds, but cash compensation is off the table. U.S. DOT rules similarly do not mandate compensation for government-caused disruptions, though carriers must refund passengers who choose not to travel if a flight is cancelled.
Steps to protect your booking now
No formal DHS order has been issued — but the threat has been reiterated at the executive level, and the window between political signal and operational directive can close fast.
- Verify your itinerary today: Log into united.com, delta.com, aa.com, jetblue.com, or alaskaair.com and check any booking that routes through JFK, EWR, IAD, or PDX. Enable push notifications on the airline app so you receive schedule change alerts the moment they are issued.
- Identify your reroute options in advance: Know which alternative hubs serve your final destination — ATL, DFW, ORD, IAH, SEA, and BOS are the most likely reroute points. Having this information ready before you call the airline saves critical time when seats are filling fast.
- Book new trips through unaffected hubs: When searching for new international itineraries, use Google Flights or ITA Matrix to filter out the four at-risk airports as connection points. Book directly with the operating carrier — not a third-party OTA — so rebooking rights are cleaner if schedules change.
- Know your refund rights: If your airline cancels a flight and you choose not to travel, U.S. DOT rules require a full refund regardless of the cause. Cash compensation for delays is not guaranteed when a government action is the trigger — but the refund right is firm.
- Monitor CBP wait times if you are already overseas: Check bwt.cbp.gov in the 24 hours before departure. If your gateway changes, confirm your domestic connection still works before you board.
Watch: A formal DHS or CBP directive specifying staffing reductions at named airports — if published in the Federal Register or via an official DHS press release — would trigger immediate schedule changes and likely travel waivers from United, Delta, American, JetBlue, and Alaska. If waivers appear on airline websites before any formal order, that is the clearest signal that carriers believe disruption is imminent.
Questions? Answers.
Can airlines keep flying international routes if CBP staffing is reduced but not eliminated?
Partial staffing cuts would slow processing dramatically rather than halt it outright — but the effect compounds quickly. Longer inspection times mean aircraft miss scheduled turn-times, departure banks collapse, and connections fail. Airlines would likely begin padding block times and reducing international frequencies before any complete suspension, so degraded service could precede a full shutdown by days or weeks.
Would EU261 compensation apply if my flight is cancelled because of a CBP staffing cut?
Almost certainly not for cash compensation. EU and UK courts consistently classify government decisions — including border authority actions — as extraordinary circumstances outside the airline’s control, which exempts carriers from the standard delay and cancellation payouts under EU261/2004 and UK261. However, airlines must still offer you a choice between a full refund or rerouting to your final destination at the earliest opportunity. The right to care (meals, accommodation) during long waits also remains.
Which airports are safe alternatives if JFK, EWR, IAD, and PDX are affected?
Atlanta (ATL), Dallas-Fort Worth (DFW), Chicago O’Hare (ORD), Houston Intercontinental (IAH), Seattle-Tacoma (SEA), and Boston Logan (BOS) are the most viable reroute hubs — none are in jurisdictions currently named in DHS discussions. Miami (MIA) and Los Angeles (LAX) handle heavy international traffic and have not been mentioned, though LAX is in California, which has sanctuary policies. Travelers should monitor whether the administration’s definition of “sanctuary jurisdiction” expands.
Is there any historical precedent for the U.S. government pulling CBP from a major airport?
No direct precedent exists for withholding CBP staffing from a major international airport as a political pressure tactic. CBP has reduced hours at smaller ports of entry due to budget constraints, but those facilities handle a fraction of the traffic at JFK or Dulles. The scale and political motivation of what is being discussed here is without modern parallel in U.S. aviation history.
