The travel industry is bracing for potential chaos as the Department of Homeland Security (DHS), led by Secretary Markwayne Mullin, threatens to halt international flight processing at airports in so-called sanctuary cities. This plan could affect major hubs such as Newark, New York, and Los Angeles, with warnings that the economic impact might reach up to $8 billion annually. Airlines and industry groups have vehemently opposed these measures, arguing that they would devastate the travel economy and lead to significant disruptions during high-profile events like the World Cup. As tensions rise over immigration policies, both the Trump administration and DHS continue to explore punitive actions against these jurisdictions, igniting debates on legality and the potential ramifications for travelers and local economies.
