The air-travel website AirHelp has released a ranking of major airports around the world.

The list includes 133 airports evaluated on criteria like customer service, cleanliness, on-time performance, and the food and shopping options available to travelers. Airports were given an overall score on a 10-point scale, with on-time performance accounting for 60% of the score, service quality accounting for 20%, and food and shopping options representing 20%.

"We chose the airports based on the best known and most used airports - but we exclude airports that we are unable to get data for," AirHelp said in an explanation of its methodology.

Eight of the 10 airports that received the lowest scores are located in Europe. One airport from Asia and one from North America also made the list.

These are the world's 10 worst airports, according to AirHelp.
