Custom Airport Reports - Survey of International Air Travelers (SIAT)


In 2020 the COVID-19 pandemic resulted in a huge drop in international air travel. Slow recovery of international air travel volume in 2021 and 2022 compared to domestic air travel is creating a substantial impact on the U.S. economy and the travel industry specifically. The U.S. Department of Commerce, National Travel & Tourism Office (NTTO) supports the industry’s recovery by tracking and forecasting market changes. This includes international traveler characteristics and volumes by total international, world region, country, and airports.

The NTTO developed annual summary files ranking the top 30 airports by international passenger volume for total and overseas air traffic based upon the APIS/I-92 data. For a quick look at the top 30 international airports for 2019 to 2022:

The NTTO provides accessible monthly international air traffic data (the APIS/I-92) for all U.S. airports. These data are updated within two weeks following the end of each month.

For a deeper market profile with highlights and analysis the 2019 Survey of International Air Travelers (SIAT) provides a pre-COVID baseline. Three reports listed below combine graphics and summary tables focused on the international visitors’ trip characteristics, demographics, and visitor volume. The SIAT survey collects detailed information on international visitors to the U.S. arriving by air and U.S. residents visiting international air destinations.  2019 specific airport reports can be developed.

These reports focus on the traveler profile and trip characteristics for travel between the U.S. and Overseas destination during 2019 (the baseline pre-COVID year). Please Note that Overseas travel does not include travel to/from the U.S. and Canada or Mexico.

The international air passenger volume for analysis and reporting by airport was based on APIS/I-92 and ADIS/I-94 data. The passenger profile and trip characteristics were based on the Survey of International Air Travelers (SIAT). There were 82,899 survey respondents that provided data in 2019 on their travel to/from the U.S. and Overseas destinations.

The NTTO’s Survey of International Air Travelers provides U.S. gateway airports with detailed market information and includes the true O&D for international air travelers, as well as airport service ratings. Custom reports can be designed for each of the major U.S. international gateway airports.

 In 2020, with the dramatic decline in overseas travel to the U.S. (-81%) when compared to 2019 record non-resident overseas arrivals and the 78% decline in U.S. travelers going abroad. With fewer travelers, the NTTO also saw a decline in the number of surveys collected. In 2020, there were 32,849 survey respondents that provided data on their travel to/from the U.S. and Overseas destinations.

In 2021 there was substantial recovery in the overall SIAT survey sample collection effort, which rebounded to 81,035 respondents for overseas travel.
