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.
The questionnaires are designed to be
self-administered by the respondents, and are distributed
at the international flight departure gate or onboard 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.

The survey is conducted monthly, specific flights are selected at random, and
airlines who participate in-flight receive advance listings of the
flights to be surveyed. These airlines are then sent survey
kits, which contain instructions and questionnaires in the
appropriate languages. Onboard personnel distribute the
questionnaire after boarding, and collect the completed
forms prior to debarkation. For the majority of
particiating carriers, data collection takes place at the airport
of international departure, where DHS-badged survey
personnel are responsible for distributing and
collecting the completed questionnaires.
