Before rushing to validate that 75% of travelers check their documents well in advance, one must consider the conditions of exit of this statement. A simple survey on Google Forms, even with 78 responses, has an intrinsic limit because people can declare an intention rather than a real behavior, especially for tasks as critical as travel preparation. For example, someone might claim to check their passport weeks in advance but in practice only do so a few days before departure, which can lead to unexpected logistical problems at the airport or border.
