 Fourth of July holiday vacations are expected to last well into the weekend since the TSA doesn't expect to see a traveler rush until Sunday. Natalie Migliore has more. TSA spokesperson Lisa Farbstein says with nearly three million airline passengers being screened at airports around the country almost every day, travelers should keep one thing in mind. Get to the airport at least two hours before your scheduled flight because there are hundreds of thousands of people ahead of you on any given airport on any given day.
