The holiday travel season has officially begun, with the TSA anticipating screening approximately 40 million travelers at airports nationwide from now until January 2nd. This marks a 6.2% increase from the previous year. Miami International Airport is experiencing a steady flow of travelers, with expectations of increased activity in the coming days. AAA predicts 120 million people will travel, mostly by car, but a significant number will fly. Weather conditions in the Northern Plains and potentially the Northeast could impact travel plans, causing delays. Airlines and airports are working to prevent past issues of travelers being stranded by over-communicating and advising travelers to check flight statuses frequently. In the event of a government shutdown, TSA employees deemed essential will continue working without pay, but extended shutdowns could lead to longer wait times. Airports are improving efficiency by managing TSA lines effectively, ensuring smoother operations during peak travel times.
