Delta Air Lines, represented by the industry trade group Airlines for America, has issued a warning about the growing impact of the U.S. government shutdown on the airline industry, which could lead to significant travel disruptions. As the shutdown entered its 15th day, concerns are rising over air traffic controllers and TSA officers working without pay, potentially leading to staffing shortages, longer security lines, and flight delays. The CEO of Airlines for America has urged a swift resolution to avoid further disturbances to air travel, highlighting that similar past events have forced the FAA to slow air traffic in key areas, causing widespread delays. The shutdown is also affecting traveler confidence, with potential declines in bookings if passengers fear cancellations or delays. Aviation groups are calling for immediate action to prevent long-term damage to the industry.
