“Air Travelers in America” is A4A’s annual survey, conducted by Ipsos, collecting vital statistics about air travel. The most recent such poll was conducted online between January 6-22, 2020, in which Ipsos interviewed roughly 10,000 adults age 18+ from the continental U.S., Alaska, and Hawaii. This included more than 4,000 adults who flew on an airline in 2019.

Background

Beginning in the early 1970s, the Air Transport Association of America (now known as Airlines for America) partnered with Gallup to poll the American public, by phone, with respect to air travel. The last such study was conducted in 1998. In late 2015, A4A relaunched the annual survey in partnership with premier online polling firm Ipsos.

Ipsos Methodology

The sample for this study was randomly drawn from Ipsos’s online panel (see link below for more info on “Access Panels and Recruitment”), partner online panel sources, and “river” sampling (see link below for more info on the Ipsos “Ampario Overview” sample method) and does not rely on a population frame in the traditional sense. Ipsos uses fixed sample targets, unique to each study, in drawing a sample. After a sample has been obtained from the Ipsos panel, Ipsos calibrates respondent characteristics to be representative of the U.S. population using standard procedures such as raking-ratio adjustments. The source of these population targets is U.S. Census 2016 American Community Survey data. The sample drawn for this study reflects fixed sample targets on demographics. Post-hoc weights were made to the population characteristics on gender, age, race/ethnicity, region and education.

Study Accuracy

Statistical margins of error are not applicable to online nonprobability polls. All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error and measurement error. Where figures do not sum to 100, this is due to the effects of rounding. The precision of Ipsos online polls is measured using a credibility interval. In this case, the poll has a credibility interval of plus or minus 1.1 percentage points for all respondents, and plus or minus 1.8 percentage points for 2019 flyers. Ipsos calculates a design effect (DEFF) for each study based on the variation of the weights, following the formula of Kish (1965). This study had a credibility interval adjusted for design effect of the following (n=10,034, DEFF=1.5, adjusted Confidence Interval=+/-2.6 percentage points).
