On this day before Thanksgiving, a constant, steady flow of passengers are making their way through Lambert-St. Louis International Airport.
Airport officials say about 23,000 passengers are going through checkpoints today.
Airport Director Rhonda Hamm-Niebruegge says so far the busy travel day has gone smoothly. She says one reason why is because children under 12 years old do not have to remove their shoes when they go through airport security.
