Our airport passenger throughput data is from the Transportation Security Administration (TSA), an agency of the U.S. Department of Homeland Security that has authority over the security of the traveling public in the United States.

We provide and visualize the airport passenger throughput data at two levels:

  1. daily US total;
  2. hourly airport checkpoint detail.

Both of them are from TSA. We update those data daily. However, whether new data is available depends on TSA’s data publishing schedule. TSA publishes the daily US total data every day with a one-day report lag. Unfortunately, TSA’s publishing schedule of the hourly airport checkpoint level data is irregular. At the ballpark, there is a two-week report lag for the airport level data.

Where do you get the airport traffic data? How often are those data updated?
