Is PreCheck worth it at PDX?
Over the same period PreCheck saved 6 minutes on average compared with the standard lane, and 16 minutes at the 6 AM peak. Standard-lane waits are usually short here, so the gain is largest at peak times.
Terminal by terminal
South Checkpoint has had the shortest standard line (10 minutes on average) and North Checkpoint the longest (11 minutes). Security is separate in each terminal, so the one that matters is the one your airline uses.

Common questions
- What is the best time to go through security at PDX?
- Over the last 28 days the standard lane has been quietest around 1 AM, averaging 3 minutes, and Wednesday has been the lightest day.
- Which terminal at PDX has the shortest security line?
- On average, South Checkpoint (10 minutes). You can only use the checkpoint for your own terminal, though, so check which terminal your airline flies from in the finder above.
- How early should I get to PDX?
To plan your arrival, use the worst hour rather than the average: at PDX that is 24 minutes in the standard lane around 6 AM. Allow that on top of your airline's check-in and bag-drop deadlines, and more on Sundays 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.
