The proportion of total spending on an overseas visit by air will vary by country. In particular, air travel prices are likely to represent a higher proportion of travel spending in low income countries, especially where air travel markets have not been liberalised. However, for the bulk of air travel in liberalised OECD markets the air travel price typically represents around 25% of the total travel costs associated with leisure travel (though the exact percentage varies depending on the length and type of travel).
