Common questions
- What is the best time to go through security at HOU?
- Over the last 28 days the standard lane has been quietest around midnight, averaging 5 minutes, and Wednesday has been the lightest day.
- How early should I get to HOU?
To plan your arrival, use the worst hour rather than the average: at HOU that is 9 minutes in the standard lane around 1 PM. Allow that on top of your airline's check-in and bag-drop deadlines, and more on Mondays and holiday weekends.

Where these numbers come from
Each airport publishes its own checkpoint wait estimates. This site reads them every minute and keeps every reading. Closed lanes are left out of the averages, and times are local to the airport. The averages above cover the last 28 days and are recalculated every hour. The posted wait is the airport's estimate, not a timed measurement, so treat it as a guide.
