Boxplots of the monthly volume of airline passengers by the duration of holidays across the world. (a) Airline passenger statistics in 90 countries/territories/areas, collated by this study from openly available data sources. (b) International air travel data based on passenger bookings, obtained from the Official Aviation Guide. The monthly volume of air travel was transformed as the rank. Months with higher volumes of airline passengers have a higher rank (from the lowest to the highest: 1–12) in each year and country.
