Counts of people, not minutes of waiting. The Transportation Security Administration publishes how many passengers it screened each hour. It does not publish wait times in this data, so we cannot tell you how long a line will take. Use this to see when the airport is heaviest, then follow your airline's advice on how early to arrive. This page uses 119 days of counts between May 10, 2026 to October 10, 2026, so it reflects May to early October, not winter or the main holiday periods.
