Abstract
As long as people and freights need to move from one place to another, the civil aviation industry will always exist. In this study, a country-based examination has been made on total airfreight transport. Also, gross domestic product (GDP) and total population data were included in this study. 50 countries were selected according to the most recent value that included the years 2018 or 2019 and 26 of these were included in the analysis which was covered in all three rankings. The purpose of the study is to find the similarities between countries based on the total airfreight transportation, total GDP, and total population. The relationship between the three parameters was examined with the correlation analysis. Afterward, the associated parameters were taken as independent variables and the total airfreight transportation variable was modeled by multiple linear regression analysis. In light of these analyses, GDP and total population have a significant impact on total airfreight transportation. To check the assumptions related to outliers, residuals are determined. To show the outliers and the similarities of the countries clearly, the multidimensional scaling method is used. Multidimensional scaling configuration shows that Turkey and the United Kingdom have similarities in terms of total airfreight numbers.
Highlights
Airfreight is a term for carrying freights in national and international transportation that includes short to long distances
In this study after defining the term of airfreight, a general evaluation was made with correlation analysis according to examining relationships between total airfreight, total gross domestic product, and total population
In addition to airfreight on a general basis, it was mentioned that civil aviation is considered under the concept of combinational airlines which is related to carrying airfreight near luggage in commercial flights
Summary
Airfreight is a term for carrying freights in national and international transportation that includes short to long distances. The other meaning of airfreight is related to the loading of goods with an air carrier. Airfreight service is the most precious one considering express loadings around the world. Just as the commercial or passenger airlines, freight airlines fly in identical routes. Airfreight, on the other hand, infers the sum to be paid for the transportation of commodities by air. When goods are carried from one place to another, the sum of the payment for the movement of the commodities is described as freight.
