The site analyzed the costs of more than 1 million flights from 80 countries to determine which destinations offer the cheapest and most expensive domestic and international flights.
The study looked at both low-cost and full-service airlines and both peak and off-peak travel dates to calculate average ticket costs per 100 kilometers of travel.
Malaysia was the cheapest, with an average flight cost of $4.18 per 100 kilometers, thanks to particularly cheap international flights on low-cost carriers, and cheap domestic fares. Bulgaria came in second, and India, Turkey, and Romania followed behind.
Belgium had the most expensive overall average for flights, at $54.63 per 100 kilometers. Chile had the most expensive average costs for domestic flights with full-service carriers at $152.01, followed by Qatar at $102.32.
When it came to international flights aboard full-service carriers, the Netherlands had the highest average cost at $43.24, followed by the United Arab Emirates at $49.13.
