Overseas to the U.S. Custom Report Background

The International Trade Administration (ITA), Office of Travel and Tourism Industries (OTTI) conducts the "Survey of International Air Travelers."  Data from the survey is used by both the private and public sectors.  It is an invaluable resource for planning and marketing and can be used to analyze behavior of specific visitor segments.  A uniquely valuable aspect of this survey is the expansion of the results to represent a defined visitor population.

Report survey results are expanded to represent international overseas travelers to the United States, based on the Immigration and Naturalization Service (INS) I-94 Form.  This form is required for most non-U.S. resident travelers arriving in the United States, and provides a count of travelers from almost 220 separate countries.  It is the best source of residency data available for travelers to the U.S.¹

Questionnaire Content
A copy of the questionnaire can be found by clicking here.  It contains twenty-nine multi-part questions, related to trip characteristics and traveler demographics.

The questionnaire is unique in its design to collect information on a traveler's complete trip itinerary, including information on every major destination visited, the length of stay and the type of accommodations utilized.  In addition, information on expenses by category is collected, as well as payment method.  The level of detail collected in these questions is not available elsewhere.

Survey Operations
Major international airlines voluntarily conduct the survey.  The questionnaires are designed to be self-administered by the respondents, and are distributed on-board flights departing from U.S. airports to international destinations.  Questionnaires are available in twelve languages: Arabic, Chinese, English, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, and Spanish.  U.S. residents and non-U.S. residents are surveyed for all destinations except Canada.

Surveys are conducted monthly, during a seven-day period beginning with the third Monday of the month.  The specific flights are selected at random, and participating airlines receive advance listings of the flights to be surveyed.  Airlines are then sent survey kits, which contain instructions and questionnaires in the appropriate languages.  Airline personnel distribute the questionnaire after boarding, and collect the completed forms prior to debarkation.  For a limited number of airlines, data collection takes place at the airport at the departure gate.

Survey Participation
Typically, 40 unique airlines participate in the survey.  Office of Travel and Tourism Industries relies upon the voluntary participation of airlines to collect data on international travelers.  While the data are expanded to represent all travelers based upon the DHS I-94 data, zero respondents times a weight is still zero.  This means that if no surveys are collected for a particular market, no weighting scheme can correct for this absence.

When reviewing the estimates developed from a subset of the survey data, users need to carefully review the number of respondents for each column heading, as well as the list of participating carriers.  The absence of an airline and lower sample sizes will impact the estimates developed for the origin and destination figures.
