Generally, mornings and evenings tend to be busier, with longer lines, particularly during peak travel periods such as holidays. It’s recommended that passengers arrive 2 hours before their Domestic flight and 3 hours for International flights to ensure ample time for security screening. Enrolling in TSA PreCheck can significantly speed up the process, reducing wait times.
