Why do international passengers typically offer a better economic impact than domestic passengers?

International passengers generally have a more significant economic impact than domestic passengers primarily because they tend to stay longer and spend more money during their trips. When international travelers visit a destination, their expenditures encompass a broader range of areas, such as lodging, dining, entertainment, shopping, and transportation, which contributes more substantially to the local economy.

Additionally, international travel often involves longer trip durations compared to domestic travel. This extended stay allows international visitors to engage more deeply with the local culture and attractions, further increasing their spending. Many international travelers may also be more willing to spend on experiences that enrich their visit, making their overall economic footprint larger than that of domestic passengers.

The other options do not capture the main reasons behind the economic impact of international travel. While advance bookings can be a factor, they do not directly equate to economic impact. Similarly, traveling in larger groups or preferring connecting flights may affect logistics but do not significantly enhance overall spending or duration of stay. Thus, the key driver of economic impact lies in the longer stays and higher expenditures of international travelers.
