Airlines and Business Groups Warn of Chaos if US Limits International Flights

• Over 20,000 international passengers land at Newark daily (including 14,000 U.S. citizens), and shutting down all 18 affected airports would impact 68 million international passengers annually and cost the economy over $70 billion
• The threatened action comes weeks before the FIFA World Cup final on July 19 in New Jersey, about 12 miles from Newark airport, raising concerns about damage to America's reputation as international visitors stream in
• Business groups warn that halting customs operations would disrupt critical cargo shipments including pharmaceuticals and semiconductor chips, with ripple effects across interconnected aviation networks nationwide

Summary

The U.S. Department of Homeland Security has threatened to halt international traveler and cargo processing at Newark Liberty International Airport and potentially over a dozen other major U.S. airports in "sanctuary cities," including Boston, Denver, Philadelphia, Chicago, Los Angeles, Seattle, and San Francisco. DHS Secretary Markwayne Mullin cited disputes with local law enforcement over assistance to federal immigration officials, specifically referencing access issues at a New Jersey detention center.

Major industry groups—including the U.S. Chamber of Commerce, Airlines for America, National Retail Federation, and U.S. Travel Association—issued a joint warning about potential economic chaos. The U.S. Travel Association estimates that shutting down international flights at all 18 affected airports would cost over $70 billion to the economy and impact 68 million international passengers annually. Newark alone processes over 20,000 international passengers daily, including approximately 14,000 U.S. citizens.

The timing is particularly critical as the FIFA World Cup approaches, with the final scheduled for July 19 in East Rutherford, New Jersey, just 12 miles from Newark airport. Industry groups warn that restrictions would severely damage America's reputation as international visitors arrive for the tournament.

Additional concerns include disruption to crucial cargo shipments, including pharmaceuticals and semiconductor chips, which cannot be easily rerouted. The Cargo Airline Association emphasized severe economic consequences from any air cargo disruptions.

Three airline executives told Reuters they don't expect the Trump administration to immediately implement restrictions. The White House has not commented on the warnings.

Key sectors affected: Airlines, travel, retail, cargo, and supply chains dependent on international connectivity.
