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.
