As outlined in Section II, the EU28 as well as EFTA countries and their ranking have been investigated with
respect to each analysed factor. As can be seen in Table 2, data on the different variables are not available for all
countries. For example, air trips per capita are not reported for Iceland, Liechtenstein, Norway, and Sweden in
the Eurostat database for 2014. These countries are excluded from the regression analysis, leaving a total of 28
observations.
