CPB
There are times when politics goes beyond the usual annoyance levels. This is one of those times. Generally, US International Traffic Ignores Political Noise.
What’s Actually Happening
On April 6, DHS Secretary Markwayne Mullin said the Trump administration is considering pulling US Customs and Border Protection officers from airports in sanctuary cities, citing those jurisdictions’ limited cooperation with federal immigration enforcement. As of April 7, no order had been announced, no list of targeted airports had been released, and no timeline had been provided. This is a threat, not a directive — at least for now.

The 11 airports potentially affected include JFK, LAX, SFO, Seattle-Tacoma, Minneapolis-St. Paul, Boston Logan, and Philadelphia. These are among the busiest international gateways in the US. This underscores both the impracticability of the move and also signals the seriousness of the threat.
How It Actually Works
CBP officers are not a courtesy service at international airports. They are a legal requirement. Under federal regulation, all international commercial aircraft arrivals require explicit CBP permission to land — granted only after passenger manifest review and CBP clearance at the destination port of entry. Remove CBP from an airport, and that permission cannot be granted. Airlines cannot legally operate international arrivals without it.
Roughly 3 million passengers pass through customs at JFK alone each month, and LAX handles comparable volumes. SFO, Boston Logan, Philadelphia, Seattle-Tacoma, and Minneapolis-St. Paul are all major international gateways for transatlantic, transpacific, and Latin American routes. The airlines serving these airports — American, United, Delta, JetBlue, Alaska, and dozens of foreign carriers — would face immediate route suspension, not delay.
The FIFA World Cup Dimension
The move could have major ramifications for the FIFA World Cup set to start in early June, with matches scheduled at venues in New York, Los Angeles, Boston, Philadelphia, and Seattle. Stripping international status from those cities’ airports weeks before a global tournament would be an extraordinary own goal.
The Political Context
The proposal is tied to a partial DHS funding lapse that began February 14, 2026, after Democratic lawmakers conditioned DHS funding on new immigration enforcement restrictions. Mullin framed the CBP withdrawal threat as a resource-prioritization decision rather than as retaliation.
Bottom Line
This is a political threat using aviation infrastructure as leverage. Whether it ever becomes an operational reality is a political question. But the aviation mechanics are unambiguous — CBP withdrawal means the suspension of international routes at some of the world’s busiest airports. Airlines, lessors with aircraft deployed on these routes, and anyone with exposure to US international gateway economics should understand what the threat actually means operationally, even if the probability of execution remains low.
The US invited the world to the FIFA World Cup. Closing the door at JFK and LAX six weeks before kickoff would be a different kind of own goal.
