As the government shutdown extends into its seventh day, US airports are experiencing significant delays and disruptions. Major airports across the country are facing staffing shortages, particularly among air traffic controllers, leading to longer wait times for travelers. Hollywood Burbank Airport has seen its air traffic control tower go unmanned for hours, while San Diego Airport has advised passengers to arrive early due to similar staffing issues. The Federal Aviation Administration (FAA) has warned that conditions could deteriorate further, with possible impacts on flight safety inspections and maintenance. Concerns are rising regarding the expiration of crucial federal air travel funds that support rural communities. Aviation officials urge travelers to stay informed about potential delays as the shutdown shows no immediate signs of resolution.
