Note that data collection at four of the airports included did not begin until October, 2006 and no wait time
information is available for these airports prior to that date. These airports are Detroit Metropolitan,
Ontario International, Cincinnati/Northern Kentucky International and Minneapolis/St. Paul International.
There are two ways to review the CBP airport wait time historical data.
1. Generally, the seasonal monthly option provides the best predictor of future wait times.
2. If you are traveling during a peak time, such as a holiday, the Date Range option will provide you with
the ability to look at a snapshot of average wait times over a shorter historical period.
