Flight comparison website Kiwi.com analyzed over a million flights from 75 countries popular with tourists to break down which destinations offer the cheapest and most expensive domestic and international flights.

The study includes low-cost and full-service airlines, during both peak and off-peak dates, with average ticket costs calculated per 100 kilometers—or about 62 miles—traveled.

Domestic flights are based on average costs from the country’s capital to up to five major cities in the country, or to cities in neighboring countries when domestic flights were not available. International flights are based on average costs from all of the international airports in the country to up to five international hubs.

India took the top spot for cheapest flights, at an average cost of $3.25 per 100 kilometers. The country's ranking was thanks to a particularly low domestic flight costs.
