Flight compensation company Airhelp has produced a ranking of 72 of the world's airlines, revealing the best and worst — and some are certainly surprising. 

The company's  sixth annual AirHelp Score rates airlines based on quality of service, on-time performance, and claim processing in order to produce an overall score.

A spokesperson for AirHelp told Business Insider that in order to ensure consistency, where data wasn't available across each of these metrics, an airline was excluded from the survey, which resulted in a ranking of 72 international carriers in total. 

Of the 13 lowest scoring carriers on AirHelp's ranking, six were European.

Scroll on for 13 of the worst airlines in the world, according to AirHelp's list, ranked in descending order by their overall score.
